From what i've read the PS3 is meant to have a 10 year lifespan prior to PS4, so no..
But we aren't ready for PS4.. anyway, it'll come with the successor to bluray and the games then will probably be around 1000GB.
probably start off around $599 again as well, no joke...
btw, i wouldn't mind another GTA in london. Kill me some wankers and be bloody proper.
