We don't know a lot about Cryptozoic, and we were initially skeptical until Kat Hunter's tweet.
Blizzard and UpperDeck recently split ways, which left the TCG's future full of many unanswered questions. And while there are still several today, the game at least has a home and some real potential for success.
Update: Nethaera hit the forums to formally announce Cryptozoic carrying the TCG. We'll be seeing the Wrathgate booster in May, and class decks will begin their run in June.
