I also don't believe Jericho's assertion that he'll never work for the WWE again, but this particular reason never crossed my mind as valuable proof of his claim's lack of validity. Frankly, I believe the former Y2J thinks the same way that I do in regards to "proper" send-offs: that they're nonsense. Jericho is in the storytelling business and the story he tells best is that of a smarmy douche who will eventually get his comeuppance. As he said in his DVD, he'd prefer people be happy to see the back of him rather than take a heroic ride into the sunset. And I commend him for that attitude. It's a level of professionalism so few have in a business with so many people who are huge marks for themselves. Jericho meeting his end with a stiff short from Randy Orton or being dragged crying from the WWE ring by security after being unceremoniously fired is what he deserves and I fully expect Jericho's last run in the WWE to end in similar dishonour.
Anyway, onto the tweet in question. It just rings of a terrible joke to me, especially the bit about dancing followed by conspicuous ellipses. If he was really closing the book on his WWE career, I can't picture him doing it with that in the same sentence to intentionally arouse ire among those who would support him with the greatest of fervour in his future endeavours. No, this just stinks of professional wrestling. And my heart is split on that. On one hand, I'll be happy to see Jericho again as he's one of my favourites. On the other, I'm a youth movement guy so seeing the back of him once and for all wouldn't bother me. While still smart and valuable to a degree, he's a relic of a bygone era who will be hindering progress if he takes a top spot for any extended period of time. Hopefully I'll manage to not to get too caught up in that and just enjoy the ride while it lasts.
The next big question is regarding where he goes if he returns. I'm sort of hoping he comes for Randy Orton at WrestleMania. It's easily the freshest high-profile bout Orton can have at this point and it's perfect organic booking. What I wouldn't do is shoehorn Jericho into CM Punk's road to WrestleMania. Punk's heat may still be fragile as he's a relatively newly minted face. Forcing the issue about whether he's really the best in the world against a returning favourite who has a great rapport with the audience might border on hubris at this point. Punk vs Jericho sounds good down the road but I hope they steer clear of it at WrestleMania 28. The margin of error makes the Punk fan in me sweat.
You raise some interesting and valid points. Don't get me wrong, I'm not suggesting Jericho requires or deserves a send off comparable to what Shawn Michaels or Ric Flair received, because you are correct, sometimes that's a little over the top and unnecessary. However, I would prefer it if it was common knowledge that if Jericho returns, it is for the final time and when he wrestles his last match, the audience knows that it is truly the end. It would not necessarily have to be a match whereby it is announced that if he loses he retires, and there's a big song and dance about it. But I would like his final match to be a significant one, against a great opponent, whereby even if it is not announced in a kayfabe sense, it is common knowledge that this is it. In the world of Facebook, twitter, etc., it would be easy to do this. Jericho has been one of my favorites for years, dating back to WCW, and I would like his final match to be one I can watch knowing it is indeed his last one. It would be OK with me if that was him getting fired, or getting punted in the head, or whatever. I would just like to be able to ejoy him one more time, knowing that that's that.
I'm intrigued by the idea of a Jericho/Orton finale. Even if it had the same conclusion, that would be OK. Otherwise, I'm not sure what Orton will be doing this March. Personally I would prefer a Punk/Jericho contest, but that's just me. Punk takes the title from ADR and carries it into WM. Jericho returns at the Rumble and wins it. The guys blow twitter up over the months in between these two PPV's, and the end result is a Punk victory and a sweet Jericho finale. Plus, tie Jericho into the whole Nash, Miz, Truth, Laurinitis conspiracy, and this could put Punk over huge as a face.
