I don't think it's going to happen.
If you want to make a PSN or XBLA game your are looking at some heavy costs. Their SDK's are 10k and their certification process can easily run you 50K. There is XBLIG but that isn't a business solution it's a hobby solution. Plus you can't even use unity on XBLIG.
I would love it if C2 was on the Xbox but the way the MS runs the Xbox publishing service I don't think it's highly likely.
The only way you will get onto XBLA is to make a free to play game and get people playing it and hopefully approach some publishers to help back your game. By the way, XBLA games cost around 750k to produce with art, programing and everything.
