IGN has posted some information about 50 Cent: Bulletproof for the PSP which is NOT a port of the abysmal PS2 version of the game.
Included are brand-new screenshots and an interview Aaron Blean, producer of the PSP version. Aaron mentions that there are 160+ music tracks and 15 music videos in this version as well as a feature length documentary for the PSP.
Word around most game sites that have previewed this, is that is actually a decent game. So if you can forget the PS2 title of the same name, and enjoy the whole “gangsta” style, this might be one to check out.
