because Sony has stated PSp is not competing with DS, they aret hat stupiud, it is competing with Ipod. Aony wants PSp to eleminate Ipod period so they can make Walkman profitable again.
Sony knows, as arrogant as they are they KNOW Nintendo ONWS the handheld market and have been proven that once again. PSP doesnt even sell very many games.
Back to PS3 remote, in all honesty, considering the rave reviews by devs and considering that even Nintendo is offering a shell for those who dont adapt right away, I would be surprised if Sony DIDNT copy the remtoe on some way or another, its just copetitive bussiness and they already are behind revolution in all aspects except HD and graphics. They dont even have a real online plan yet so if they dont do something to make Nintendo look worse than them they are screwed.
