PS4? Not for, at least, 5 more years, I hope... With all the power and technology available, and the high price of games, developement etc., Sony and Xbox decided to upgrade their consoles with 'motion' hardwares, which is a very good choice and just keeps our consoles alive for more years to come, also offering a broader range of games (casual, hardcore, etc.).
PSP2, I hope! All the game exploits, lack of functionnalities, piracy... this killed the PSP. New hardware with better performance would be much appreciated. PSPGo = big flop. PSP1000, PSP2000, PSP3000 = almost all the same.
I hope they do it well now..
