I think it's wiser for Sony to wait a little till 3DS launches to reveal their new iteration of the PSP. If they can make sure it has 2 analogs and more powerfull hardware, they are good to go into the handheld battle all over again. The longer they wait, the more powerfull will it be (and I want AA in my next handheld, I really do).
MY HYPE LIST: 1) Gran Turismo 5; 2) Civilization V; 3) Starcraft II; 4) The Last Guardian; 5) Metal Gear Solid: Rising
