I really don't care for Chris Jericho but it would be cool to see him on tomorrow RAW. I thought he might have sent it just to tease us and he wont really return. But then i thought it is also past 2 in the morning and no one will really see if it.
I don't think he was implying that he would be there, maybe he was excited to see what the Rock was gonna do. Or maybe Punk/Ryback. Doesn't mean he has anything to do with the show just because he's excited.
