I haven't seen this reported on here, so I figured I'd give it a shot.
I don't know the posting rules so I'll generalize it, I know a few of the more reputable sites have claimed Vince wants Jericho back for Mania. Also on Jericho's MySpace page he ended with "JerichoMania is running wild".
So with Trips down and out, could this be the return of Y2J?
And does his vague quote have anything to do with Hogan or just with Mania in general?
I wouldn't read too much into it. Jericho has a past of playing pranks on the internet, like the picture of him posing in front of the TNA logo and other similar events.
Have you guys SEEN Jericho lately? He's hardly maintained a "wrestler" body-build, so it would take a few months before it would even be worth SHOWING him on tv. Either way, don't hold your breath. And rule of thumb: never EVER believe anything Jericho hints at. He's full of sh*t ten times out of ten whenever he drops wrestling-related hints.
