I somehow don't mind that the DS sold much more than the PSP. I have both handhelds and the PSP is the clear Winner for me. Kingdom Hearts Birth by sleep, Final Fantasy Dissidia and Crisis Core blew me away. The DS Games (FF 12 Revenant Wings, Tactics Advance 2, etc) were also good games, but the PSP games with its technical advantages felt much more intense for me.
After I have finished KH BBS I will try out DQ 9. But every time I buy a Square Game for the DS I think I would rather have it for the PSP, since the storytelling could take advantage of better graphics, cutscenes and voice acting.
I might be wrong, but I think the PSP2 will also be more powerful than the 3DS. So if the 3rd-party-support is still strong with the psp2, it will be my winner. But since the next Kingdom Hearts is already heading for the 3DS I will have to buy it anyway.
Sometimes I wonder, when I see people discussing sales figures of the DS and PSP, what they would choose if the next game of their favourite franchise (KH, Metal Gear, Resident Evil, etc) would head either to PSP or DS (and they own both of them). My clear answer would be PSP. There are games like TWEWY which benefit from the DS controls, but regarding storytelling there is a huge gap in favour of the PSP. I just can't see KH BBS, FF7 CC or Dissidia for the DS.
