not to mention Star Wars: The Force Unleashed is gonna look 100x better on the PSP than the DS, by what i've seen of the screenshots... of course the best version will be on PS3 with the 2nd best on X360, but as far as portable versions go the PSP will be the better choice for video and audio, though the DS is gonna incorporate a cool way to control the saber with the touch screen, but the graphics are awefull and the sound naturaly not as good as the PSP... also PSP has Castlevania: The Dracula X Chronicles, Star Wars: Battlefront Renegade Squadron, & Guilty Gear: Judgment (some of the great games in my collection that were not mentioned yet)...

(Disclaimer: i own both systems and will never give an unfair opinion, as both systems have their good and bad points...)
