They've also revealed that beating the Heroic versions (much more difficult wings unlocked after completing the normal wings) will reward new card backs!
Let us know what you think in the comments below!
Update: They've also revealed the EU pricing in a separate post: Individual wings are 5.99 EUR (4.99 GBP), the remaining four after the free wing are 17.99 EUR (13.99 GBP), and the full set is 21.99 EUR (17.49 GBP). The gold costs are, of course, the same.
Update: Zeriyah revealed on Reddit that the golden versions of the Naxxramas cards will be obtained by crafting them after you've gotten access to the normal cards by completing the wings:
Greetings everyone! Good to see everyone chatting about our latest announcement.
A big question that we've seen pop up with this blog is about golden cards. Where do you get them?
When you unlock the non-golden versions of cards from each Naxxramas boss, golden cards will be immediately available for you to craft using your Arcane Dust. That's it!

We’re skimming the slime pools, stitching together our finest Abominations, and preparing the Necropolis for an Adventure you’ll never forget—Curse of Naxxramas is coming, and we know you’re just dying to get in and play! In today’s blog, we’ll discuss the details on how you’ll access Curse of Naxxramas, and unveil the Naxxramas Heroic Mode.
Your All Naxx-cess Pass
Naxxramas is a floating necropolis, home to a host of undead bosses ready to challenge worthy opponents eager to test their card-slinging mettle. To undertake the challenges that lie within each of the five wings of the Adventure, one must first gain access to their secrets. But don’t worry too much about the price of entry—much to Thaddius’ chagrin, it won’t cost you an arm OR a leg.
Naxxramas will open its gates one wing at a time, with a new wing opening each week. The wings of Naxxramas will open in the following order: Arachnid Quarter, Plague Quarter, Military Quarter, Construct Quarter, and Frostwyrm Lair.
Players who begin their adventures in Naxxramas during the launch event will gain free access to the first wing: the Arachnid Quarter. The launch event will last roughly a month or so, meaning you’ll have plenty of time to get your foot in the door—we’ll have more details to share about that later on. The web-choked corridors of the Arachnid Quarter are home to the bosses Anub’Rekhan, Grand Widow Faerlina, and Maexxna. Defeating these bosses will add new cards to your collection and give you a taste of the dangers that await you deeper inside Naxxramas.
After the Arachnid Quarter, the next four wings can be purchased for 700 gold per wing or $6.99 per wing. Players can earn the in-game gold needed to unlock the next wing of Naxxramas by completing various quests or emerging victorious from the Arena, or they can choose to unlock the next available Naxxramas wing using real money.
If you’re looking to swing open multiple gates at once, Curse of Naxxramas bundle packages are also available. Spiders are just so good at making things into neat little bundles. . . .
Keep in mind that purchasing Curse of Naxxramas wings in bundles does not open or grant access to those wings faster than the one-wing-a-week schedule, but it does ensure that you’ll be able to dive into the next challenges as soon as they unlock.
If you play Naxxramas during the launch event and decide to purchase the remaining wings with real money, you’ll only have to purchase the 4-Wing bundle to access the remaining wings once they become accessible.
If you unlock additional wings with gold and wish to purchase a wing bundle at a later time with real money to unlock any remaining wings, you can still take advantage of the bundle pricing. For example, if you enter the Arachnid Quarter during the launch event and unlock it for free, then purchase the second wing with gold, the remaining three wings can be purchased with real money at the 3-wing bundle price listed above.
Remember to enter the Necropolis during the launch event so you don’t miss out on all the creepy crawly fun that awaits you in the Arachnid Quarter—for free!
Once you’ve defeated all of the bosses within any given wing for the first time, you’ll unlock the Heroic mode of that wing. Heroic mode bosses are significantly more difficult than their normal versions, and they will prove to be a challenge for even the most veteran Hearthstone players. Defeating all of the bosses in Naxxramas on Heroic mode will unlock a new card back for your collection.
The undead horrors of Curse of Naxxramas: A Hearthstone Adventure are dying to meet you. We hope to see you creeping through the necropolis with your own “All Naxx-cess Pass” soon!
First, let's start off by quoting something I mentioned yesterday about golden Naxxramas card acquisition:
Acquiring golden cards from Heroic Mode bosses was actually something we had in-game during internal testing. We actually received a lot of negative feedback on this method of golden card acquisition. Like I mentioned, Heroic Mode bosses are not easy, and it felt really bad for people that felt like they could never get the golden versions of Naxxramas cards. We made this change to make things more accessible for everyone.
So, crafting golden cards was always a part of the equation during internal testing when it came to Heroic Mode. However, you were not able to craft golden versions of a card until you defeated the Heroic Mode version of that boss. Getting a golden card as a confirmed drop from a Heroic Naxxramas boss was never a part of the equation - they have always been craftable, but the ability to acquire and craft them used to be through defeating the Heroic Mode version of that boss as opposed to just getting the non-golden version of the card through Normal mode in order to craft the golden version.
This didn't feel like a good reward for defeating a Heroic Mode boss in Naxxramas, so we took out the part where you had the defeat the boss on Heroic first to craft the card. In this manner, it made acquiring the golden version of Naxxramas cards more accessible to everyone.
This was not explicitly clear that crafting golden Naxxramas cards has always been a part of the equation in my initial post, hence the confusion that has manifested. For this I apologize - I hope this explanation helps clear up what may appear to be contradictory statements, but was in fact simply just omitted information in the initial post, where assumptions could easily be made.
