They didn't actually say that...anyway I don't think it'll be as good as the PSP. It may have a load of cool features, like a stylus-touch-screen-pad, but when playing that metroid game it's going to seem a bit clumsy don't ya think. And you can only look at one screen at once. Finally, comparing the graphics I can see that the PSP's graphics look better.
