Well it's late but here is the news I picked up on while running around on Sunday at c2e2 2012.
Jamie McKelvie will take over art duties on The Defenders with Matt Fraction with Issue #8.
In the summer Thor and Journey Into Mystery will cross over bringing the return of The Fire Demon Surtur.
Cullen Bunn and Paul Pelletier are going to be the new creative team for Wolverine with Issue #305
By far the craziest news from Marvel at C2E2 is that Gambit will be receiving his own Ongoing book by the team of James Asmus and Clay Mann. Not really a Gambit fan but I might buy this because the work writer James Asmus has done on Captain America and Bucky.
