What? After all the hype of the PSP, how it was the must have handheld, Nintendos dominance was over. that is what was in the press, in the homes and in the play grounds.
Sony had it wrapped up, problem is they screwed up majorly. with the shortages around christmas they gave it to nintendo on a plate. people had to think differently they had no option and guess what they liked it.
the DS success was not because of the GBA, sure that was a factor, but that said should the PSP not have cleaned up because of the PS fan base.
With the rev i think the DS being innovative will had a major influence. If done right nintendo can "hore" the DS to gaurentee rev sales.
