So there is alot of buzz out there that Sony is about to launch an update to the PS3 firmware that allows for minis to be playable on the PS3.
My thoughts on this: While the minis are better suited for quick pick up and play gaming on the PSP, the PS3 audience would expand the minis user base and hopefully bring in even more developers. I think this would be a very positive development, for Sony, small developers, and gamers alike.
