Well, i hope PSP2 is released as soon as possible. But for PS4 i hope it's released just in 2013 or later.
I would like PSP2 to be a anti-piracy system just like PS3, and uses neither memory cards (Memory Stick) for games or be DD only. Optical midia for handelhelds just aren't a good idea. A Oled screen, hardware powerful enough to handle 720P games, nice speakers and battery to hold for more time.
For PS4 i really don't know what i want, the only thing i know now is that it should both motion controls and classics controls and have 1080P native as standard for all games.
