Chris Jericho is leaving? after Night Of Champions (spoiler warning).?

his contract did not expire in 31st of september 2009 its 2010

What you say is correct, except it is 2010 and not 2009 when his contract is up.

He has said he doesn't want to retire yet. He says he still has a few years left and wants to continue to wrestle. Sure he wants to take some time off for this tour, but he wants to continue to wrestle as he has said several times. The problem with that is, the wwe really hasn't offered him a new contract. Vince was mad that he was hosting the game show (I forget the name of it), even though at first the wwe told him it was okay to do the show. So then after he decided to host it, Vince came back and told him he couldn't do it. But by the Jericho had signed to do it, so it was too late to back out. But Vince has still been holding that against him.

So if he wants to continue to wrestle but the wwe doesn't give him a new contract, that tells me he could end up wrestling for someone else.

I don't know what he will do, but he made it clear he doesn't want to retire.

that is exactly what i have said many times. i think that he will tour with fozzy for a while and he will probably decide then if he will go back in the ring. i kind of have a feeling that he won't because he has said many times that he had other interests that he wanted to get more involved in. i don't know if he will retire but he is definitely going to take a break for a while. if things go well with fozzy's tour then he may just retire from the wrestling business altogether. he has left wwe a few times before to do things in music and later came back so i seriously doubt that he would jump to tna since wwe has always taken him back after his absences.

Chris Jericho is the BEST and better win the WWE Title at Night of Champions but I think he'll have it for like 2 weeks and leave for a while

Well I've just read on a website that Shawn Michaels (HBK) is a possibility to be Jericho's partner. They have said this because Jericho has apparently hinted he wanted a clever, devious, and a partner with a great winning mentality. They think this describes HBK really well and think he could be a possibility. I know these two have had a bitter and nasty rivalry in the past, but I could see HBK turning heel and joining Jericho as Unified Tag Champs. We would be seeing a HBK every week who has a bad attitude and a HBK who has just flipped over the edge and gone insane. I think it'd be great for this to happen. In ways it is unlikely to me that it will happen, but in other ways, it seems like it actually could happen. Wishful thinking might come true, you never know...

Jericho will return as a face to win the 2011 Royal Rumble thats why he is leaving (storyline wise now)

He's not going to TNA or any other wrestling promotion. Fact.

He will return as GM of Raw one day.

Take my word for it.

Nope he probably get suspended (FAKELY) then he we come back or something
