There is always the possiblity that the media is speculating! Its not unheard of.

however, if they do do an HD remake of ANY of the Wipeout games, i would be hoping for Wip3out. Pure (although i dont have a PSP and ive only played the demo on the Stealth UMD) didn't do it for me im afraid. Having said that, im getting a PSP so i can play on Kai.
