People have to remember a few things before immediately assuming Jericho is coming back.
1. He is contractually obligated to DWTS even though he has been eliminated. That's why he put such a hard press on "keep me on, I'll be back sooner!" If he were to make it to the finals, he'd still be on TV every week. Now, we have to wait until his last appearance at the finals. So, those hoping he pops up Sunday can put those to bed: he still has 6 weeks left at DWTS, even if he's not competing.
2. Jericho has a HUGE European tour coming up with Fozzy this Summer, so even once DWTS is over, he can't commit to a comeback, as he'd be gone almost immediately after. Couple this with the talk that they will be recording their new album after the tour, and that puts Jericho out until at least Summerslam.
3. Who says Jericho doesn't get offers for TV/movies after his stint on DWTS? He's made it well known that he wants to foray into Hollywood, and his Downfall show may get picked back up due to his appearance on DWTS, so guess what? More time off.
I would LOVE to see Jericho back. He's infinitely entertaining and the main reason I became a wrestler. However, he's going to be too in-demand for the WWE schedule, so even with a comeback, he won't be utilized the way we want since at any given time he can just waltz out for another project.
Face it kids...the send-off we got was the half-assed DVD set released back in September (yeah, it was OK, but both his books are a much better, more detailed story about his career, and the lack of Benoit on the DVD crippled the match content as all of Jericho's greatest matches, sans his feuds with Mysterio and HBK, were with Benoit) and a ginger punt to the head via Orton. Would I love to see him back and welcome him with open arms? Absolutely...but those chances are very, very slim, especially at (approaching) 41 years of age.
