I thought it might do, but now...I'm not so certain. The 3DS is going very strongly, and the market it needs to sell well in (Japan), the 3DS will have a Monster Hunter game and another in the pipeline, and an entire holiday advantage (I mean, why launch with only 1 week left?).
It will have a nice cosy start, much like the 3DS', but it will have the same problem- not distinguishing between the PSP and itself. There just isn't enough difference for the average person to tell.
So, unless Sony puts a helluvalot of cash behind it (which I doubt), it'll be a rinse-repeat of this generation. I hope otherwise, but so far, it looks set for that. And a couple strong lauch games won't change that (remember how Nintendo said they'd be 70+ developers on the 3DS in the first 6 months? Things get delayed, cut or even cancelled. It happens. I see the same thing happening to the Vita).
My guess? It'll sell around 6-7mil Year 1 (not including 2011) WW. And the 3DS will sell 12mil.
