I don't really care if they have a touch screen if they don't focus to much on it, but I have no faith in the Sony developement to do so. And the game thing didn't work because PSP doesn't really have many worthwhile titles by comparison, regardless of the superior hardware.

Honestly if it wasn't for the fact that it would basically leave the handheld market in a monopoly for Nintendo, I'd say Sony should just drop the PSP all together and focus more on what they do better, console gaming and other such products of theirs.
