The best handheld games are designed with the intention of being handheld games, so porting those games to consoles is usually a bad idea (even moreso than porting console games to handhelds). The NES and Gameboy were not terribly different in terms of power, but most of the Gameboy's best games were not availible on the NES. But would you really want to see this blown up to scale on your 30" TV screen? Purely a promotion for the upcoming movie, nothing more.

PSP also has limitations that must be worked around (less power, battery consumption, load times, one joystick and 2 less buttons, etc.) that make PS2 ports of PSP games seem somwhat underwhelming, as was the case with Liberty City stories and Vice City stories on PS2. A game like Metal Gear Solid: Portable Ops would not work on PS2 because it's designed around a tiny screen and the presumption that you'll be playing it for only a few minutes at a time. Ideally handheld games are played in small "bursts", which is where game design for PSP differs greatly from PS2.
