It's a little too close to Mania to get him involved in a serious capacity right now, particularly when he's just doing silly things like "dance-offs" or whatever. It's really not a new thing for him to be doing either, he's been making frequent appearances at house shows every since he disappeared from television. He was being advertised for the house shows in Canada back in September. I don't really see this necessarily as a precursor to him having a larger role on television, just that he's still there and doing little things for them.
I wouldn't mind him coming back and getting more serious after Mania though, they'll have all the time in the world to fix something up with him then. They should really steer away from perpetuating the Vince McMahon-esque character he was doing last year though, which is why I don't really like the idea of turning the Shield into a poor man's Corporation. But in fairness, he's nowhere near Mike Adamle's level in the comedy department either.
