While not official, there are hints due to solicitations that Red Hulk's series might not pick up after the Mayan Rule saga. BUT, that depends also on AVX, because it seems his fate lies somewhere in his involvement with AVX.
But for Hulk, it's very, very vague. Apparently after Jason Aaron's run, big things are happening for The Hulk. I don't know if it's just for Big Green or all the gamma dudes, but big things are coming.

All I know, the Hulks and the AVX thing are connected.
