I cant scan in images but in the latest edition of PSM3 (issue 128) on page 26 (the insider) it says:
"PSP2 is looking increasingly certain, after being pretty much confirmed by Lost Planet 2's Jun Takeuchi in this very magazine. The new handheld is rumoured to have two camers's (one facing forward) and a touch screen, although will still retain the familiar button layout. Let's hope it has two analogue sticks, eh?"
I can't find the article that they're refering to about Takeuchi confirming the PSP2's existence, but when I do I'll post it up here for people to read
