Sounds stupid but I hope he doesn't. I'm just being anti-WWE biased but really, unless you're built like frickin Lashley you're not going to get much of a push. You could make arguments for a guy like London I guess but he's basically in a little niche, he'll probably never get fired but I'd be surprised if he achieves even 1/2 what Mysterio has. With Punk it's too early to tell, but he arguably has/had the most charisma of anyone on the indies, so he probably has a shot.
I just fear that Claudio will get stuck on Raw with some retarded gimmick and be jobbed out for 6 months before getting released, while he could've been basically ruling the US indies and maybe even getting a shot to work Japan due to his ever-rising profile. Oh, and no more KOW
