Lost among the mountain of new PSP games in Sony's E3 press conference, Fat Princess made a brief appearance squeezed onto the smaller screen of the PSP. Was this a sneaky announcement of a PSP version of Fat Princess? For now we will classify this as a rumor until it is confirmed by our E3 team.
Looks like the title is "Fat Princess: A Fistful of Cake", and it is listed in Sony's press release for games they are showing at E3. Brilliant!
