i think you're crazy. A) as you said, the 360 didn't sell any where near 14M the previous 2 years and B) so far this year 360 is down YoY. 360 should have an excellent year software wise but tons of sequels and a new IP aren't going to make hardware fly off the shelf especially considering sony/nintendo are having big years as well.
the only wild card is natal...and i don't have faith in it. at least not yet.
