iPhone could be next PSP or DS

Take a look at this video of what looks like crash nitro kart for the iPhone. The graphics are way better then the DS and comparable to the PSP. Seems like apple unintentionally is now in the gaming market. Imagine a brain age port for the iPhone. You could practically port Nintendo DS games and remake them for the iPhone and it would most likely be better. I always thought two screens was a gimmick but touch games I hold in high regard. If apple can keep this up maybe then can officially jump into the gaming business.
