Some really big news has been released today.
First off, the current Thor title is going to be renamed as Journey into the Mystery, and it's going to be written by Gillen and drawn by Doug Braithwaite! Loki is going to be the main character working from the shadows and assembling teams to do his bidding etc. And not just Asgardians, but cosmic, magic and god affiliated characters (Mephisto, some Chaos War recruits etc.):

The main Thor title is going to be relaunched as The Mighty Thor and the creators are Matt Fraction and Oliver Coipel:

The first arc is called the Galactus Seed and it's going to be Galactus attempting to consume Asgard -the last time he tried Odin chased him off supposedly- because of a seed Thor pulls out of the World Tree.
Surfer vs. Thor, and Galactus vs. Asgard. Kind of split on this because on one hand it could be potentially really fun but I have absolutely no idea how Matt Fraction views Thor in relation to other characters or powerhouses much less Asgard.
I'm hoping it's mostly Odin vs. Galactus. I'd hate for there to be some plot device that prevents them from battling. If his current run is any indication, Surfer and Thor are going to do more debating and less fighting.
Looking forward to Gillen's book more so far.
