Previous datamining suggested this would be the case, and it makes sense that the mount originally sold during WoW's 20th Anniversary would return for the 21st anniversary as well. This sale runs through January 5th, though the mount is otherwise unchanged from last year, featuring the same $90 price tag.
The mount offers access to the Auction House and a mailbox.
Though publicly derided due to the high cost and near-exclusive services provided, the $90 store mount proved to be obscenely popular, speculated to have generated over $15 million in sales over the three months it was originally available.
While the mount has also arrived on the Chinese store bundled with 2,000 Trader's Tender alongside several other promotions, including two customizable mecha-panthers and WoW's first flying vendor mount, the NA/EU version does not offer any extra bonuses. On the other hand, the Chinese price of 888 RMB is also closer to $125 USD, representing a significant mark up over the normal $90 price tag.
The Chinese version comes with 2,000 Trader's Tender, though at an increased price.
