no i wouldn't play ps3 games on a mobile device because that's why i own a ps3. the only games i'm interested in to play on a small screen are games i play when i take a shit^^ and that are only simple crap games.
but if i would have fast enough internet i would hope to get all the future ps3/ps4 games to stream without lag on my pc or mobile device connecting with the tv per hdmi, i wouldn't need to buy a ps4 then (i really don't care about owning a disc or something so yeah, streaming would be enough for me if it would work even in online matches)
