No thats not the next PSP, its just a sony ericsson gaming phone.
The PSP2 probably called PSP Two is said to keep the overall same design with improved features such as a slot loading UMD rather than the eject method at the moment, better battery life, more vivid screen (same size) built in flash memory probably in the 4GB range, pressure sensitive buttons, maybe also slightly smaller and lighter.
But all this is up in the air at the moment, I never considered buying a PSP ever until I heard about the PS3 1.8 update and the fact that your PSP can become your PS3 anywhere in the world!! (apart from play PS3 games)..... and that really sold it for me!
