Well, after thinking how it would be possible for people who own psp's and psx games, i thought of a rather simple and ridiculous idea
Sony could make an ultra slim dvd drive which is connected via USB cable. a seperate piece can be attached to function as the L2 and R2 buttons (like how talkman's microphone works). with this, psp owners can play VCD's, DVD's, PSX and PS2 game son their bifty console, and eceryone will be happy even if they charged 100 bucks for all these external parts. (and even if they needed a firmware 3.0 to work this.
