omg, you people need to relax. I doubt any of you live in japan so why does this matter? By the way you guys talk, you'd think ds is this sucessful all over. Give it a rest with all the sales threads. Grow the hell up grown-ups! AHEM, now, psp sells well because it does more than just play games. Sure it's a game system too but truth is it does more. PSP is also in a different class of it's own, attracting a more mature group. Unfurtunatly this hurts the main handheld fanbase, kids. Truth is DS sells are very much like gba's but with the new approach of the touch screen, more adults, mainly female, flocked to it do to it's new simpler gameplay. That's where you get the the slightly improved sells compared to gba. Also, ds looks simple and inexpensive. Perfect for it kid or cheap thrills where as psp looks expensive as hell and complicated with all the pieces to buy(memory sticks, ect.) Not perfect for a kid. When psp gets more games, things will improve game sales-wise. But what really holds it back is price as a whole. Let not forget ds is still a gameboy, those sells are to be expected. Revolution will not be affected by this and here's why...simplicity. With ds the touch screen makes things easier and it's doesn't really change gamplay, revolution looks to make things complicated and annoying changing gameplay into a ddr environment. People want to be relaxed when playing most games, not swinging things around. But will see...the furture is a pickle to predict. It's been said before ds and psp are not in the same market. Im sure sony thought sells would be better but hey, they are doing pretty well.
