First of all, the PSP in '10 is an unconfirmed rumour. It may well be true, but it could also not be.
I suspect Nintendo will want to wait long enough that they can release an affordable DS2, which can play ports of Wii games. Because I suspect the DS2 will have motion sensing capabilities (touch screen capabilities as well, because Nintendo always provide a generation of backwards compatibility with their portables)
Being as the PSP is more powerful than the PS2, it seems fairly likely that the PSP2 will be more powerful than the Wii, and thus more powerful than the DS
