Hrmm, my 2008 predictions are pretty close to yours.
I'm about the same on the Wii, PS3, 360, and PS2. The DS I think you overestimated the drop some, and the PSP I think you underestimated the drop some.
Reasoning:
The chances of the DS not blowing away its 2007 Japan sales in 2008 are very low. You are grossly underestimating the effect Dragon Quest IX will have on the sales of the system in that country. By at least 1 million units in 2008 I believe. Other than that, I would say it will fall some in NA and Others, but it will also have a price drop, which should keep it at almost it's 2007 levels.
The PSP sales drop should be much larger than you are predicting. Every major PSP game that would affect the Japanese market is out. The biggest hope for a turn around was Crisis Core. The new Slim has been released, the price has been reduced, and Sony has played their hand out in that country. I would expect Japanese PSP sales in 2008 to be about 500K below your prediction.
Other than those points, in general I agree with your predictions for next year. Good analysis Source. I appreciate all the work you put into it.
