http://www.gamestop....mory-card/98469 Take a look at the bottom: Sony has already stated that some games will require them in order to run, but have not stated about how much space they'd take up. It sounds very clear to me that you essentially have to install the full game onto the memory card for the games that require them. This.... would be TERRIBLE news if true, since the memory cards are so expensive. EDIT: It could be referring to an "install required" game. If the PS3 can require 6GB+ to install a game (Skyrim, I.E.), then the Vita could certainly require 1GB+ to install an "install required" game.
