It depends solely on how good Natal is and how supported it will be by devs AND consumers. If it's awesome, the 360 can take on some of the Wii market (I'm NOT suggesting it becomes that popular, btw). Then yes, definitely. If Natal flames out in a ball of smoking wreckage? Then they are in trouble, because MS has put a LOT of eggs in this basket.
But you know, everything MS has gambled on has worked fairly well. There are hits and misses, but for the most part they have made good choices. I don't think they'd go "all in" on natal if they didn't think they had something strong.
We shall see. I am a huge consumer of 360 games and Natal doesn't really interest me right now. But to get to 70 million, it's not me that they need to buy in. It's soccer mom and high school kid.
Can't we all just get along and play our games in peace?
