Compared to Japan the Playstation Store in North America is rarely updated with new PS1 games. Perhaps that's about to change. The ESRB has a rating up for Wipeout XL as a PS3/PSP game and Wipeout XL originally came out as a PS1 game. Unless Sony is planning a remake (very unlikely!) of Wipeout XL the PS1 game is coming to the Playstation Store, hopefully with a handful of other titles.
