Dunno if it's just me, but honestly I can't imagine playing epic games on a handheld. I just don't have the time to look at a handheld for so long.
But the PSP/DS do still look exciting, I'm just a bit worried about the games to be released on it. If it's games like FFVII, and MGS then I probably won't play them because they take way too long to play.
That's why I love my GBA and Yoshi's Island

That game is so fun.
