COD 4 on the psp?

I know the call of duty roads to victory was alright if that, but the cod4 was tight for the ps3 and it looks pretty cool for the ds. if they could make it for the ds way couldnt they have done it for the psp. the traliers for the ds looks good, i mean u got a jeep chasing and shooting a truck with someone shooting back, shooting from a black hawk. it looks good for a portable. i wish they would have done it for the psp i know it would have been better. anyone else seen it and thinks they should of made it for the psp.

ya I didn't see why they didin't make it for the psp. The ds version is cool but i bet it would be a lot better on psp. It would have been a lot fun.:(
