It depends on a number of factors. I've theorized that we might see a $25 cut this year depending on Microsofts actions. A $275 price point and a fall release for GT5 would probably translate to about 15 million or slightly more this year. If that were to happen than even if it went to $199 next year I can't see it being up next year although I can't see it being down by a whole lot either, maybe 14-14.5 million. Also I really don't know how to account for 3D or Move. I don't think either will be a huge success but I don't see them utterly failing either.

When more people realize that the Xbox 360 is nothing more than a PC with a high failure rate.

fiscal 2011 (april 2010 to march 2011).
if you want a calendar year, 2010...

When it drops to $199 that would be it's best performance.

If it gets a decent price cut this year (pre Christmas $50) then I think it'll peak this fiscal year. If not than the next fiscal year will be its peak assuming it gets a price cut

I don't think it will peak at $200, if it hits 250 then the next year 200 it might have a two year peak but I think it'll peak at 250

I think someone also said it, if there is a price drop to $199, then the year after that will be the peak year. I suspect that'll be 2012.

However, a caveat, if the price drops to $199 after 2012, I believe it won't matter, the peak year will then have been 2011.
