WWE.com has an video interview up with CM Punk, who says he's going to find a partner and go after Rhodes and Dibiase and wont be satisfied until he has taken away their titles, since they took away his title.
This could lead to a good angle, but it shows that Punk is really out of the WWE title picture.

I have a feeling it could be Cena/Batista/Evan Bourne(hopefully Bourne). I don't think he's out of the picture just yet, he's just following up on a grudge then he'll probably go back to the world title imo.
