That's my crazy prediction.
Following the Natal launch, the Xbox 360 will be the top selling console every month for the rest of the generation (excluding further price drops for PS3/Wii in the future).
I don't expect anyone to agree with me at first (except maybe selnor edit: and starcraft). That's the whole point. That way, when it actually happens everyone will say "omg, OkeyDokey was right. lol, look at the posts on the first page calling him a nutcase" and we'll all have a good laugh.
I actually think it could happen, FYI. For these reasons:
-Early reception is overwhelmingly positive
-3rd party support will be strong
-It will be bundled
-Hype will be massive following the E3 2010 blowout. It will get a ton of awards and mainstream media coverage
-Microsoft will put all their weight behind possibly the biggest videogame related marketing push in history. Will be marketed towards families and casuals
This should be fun.
I'll make a list of supporters so that in the highly unlikely circumstance that I turn out to be wrong, I won't have to be alone in my shame :P
