Course your all assuming that it would be Raw side in the Chamber.
I have mixed feelings on this right now.  Chamber match not for a title just seems odd.  And doing it on a PPV where there no doubt will already be a WWE Title Match, a World Title Match and an ECW Title Match, again seems odd.  I think the right idea last year of having Cena & Michaels take on Batista & Taker was the best course of action (though that also had a lot to do with the fact that they booked 2 face vs. face Main event title matches)  I actually wouldn't mind seeing a 6 man tag main event this year at the main event for NWO with all 3 champions and there respective WM opponents.  Weather it be Champions vs. Challengers match (ie using the current title scenes, CM Punk, Orton & Batista vs. Morrison, Jericho & Edge) or just faces vs. heels (again using current scene CM Punk, Jericho & Batista vs. Morrison, Orton & Edge).  But elimination chamber ontop of your main event matches seems like too much to me.
		
		
	 
I have to agree with pretty much everything you said there, This Guy.  The idea of deciding the second (of three) #1 contenders via EC seems way over the top, and would only be used to push a big-time fued such as Taker/Edge or something.  You wouldnt have a guy like Kennedy win an EC, then go into WM 6 weeks? later to win/lose his title match.
With the idea of a six man tag, This Guy, a triple threat tag could also be in order - maybe a "see what brand's ME will be the best" kind of situation...
If they have this EC at NWO, what will the champion be doing?  Ending a current fued, having a no-point fued, or nothing?
I spose my predictions for SD and RAW would be:
HHH/HBK/Umaga/Kennedy/Lashley/??? - With Orton still being champ
Edge/Taker/Kane/Finlay/Henry/Mysterio - With Batista still being champ
