Sony unveiled their PSP lineup for 2009 today, and it contains a number of major games and franchies. Assassin's Creed is on the way, as is a portable version of LittleBigPlanet , which will still allow players to share their levels with the community. A Motorstorm game set in Alaska is also coming, and Rock Band: Unplugged is in development as well. "There will not be a peripheral attachment available... Instead, all input is handled by the 'Left,' 'Up,' 'Triangle,' and 'Circle' buttons. The player can switch between guitar, drums, bass, and "vocals" (although he won't physically be singing, merely tapping buttons) using the L and R shoulder buttons. ... The player can actually choose to switch instruments at anytime, but switching prematurely will cause him to lose his multiplier."
