Rumors going around is that the date was pushed back to 5/30 but still waiting for official confirmation on that :(
Here is your official confirmation. Molten Core releases on 5/30. We have a bunch of web content coming up very soon (product page, spoilers, crazy info page, etc.). You'll start to see it this week, definitely. I have a MC raid deck on my desk right now, actually. I got to play it against some other members of the brand team on Friday, and it was a blast. There were four of them, and they got all the way to Ragnaros, and then he wiped the remaining two players out on the turn he came out from being submerged. Maybe I've said too much...
