PlayStation 3 system update 3.15 includes a feature that allows PS3 owners to play bite-sized PSP minis. There is already a way to play Minis and PSP games on a TV. All you need is a PSP video out cable to play Zombie Tycoon on a bigger screen.
It seems like Sony is adding Minis to the PlayStation 3 to broaden the market for their tiny title. Perhaps, Minis will be the PSN equivalent of experimental Xbox Indie Games.
