I'm not entirely sure of the direction sony would take with it's next handheld but your ps4 predictions seem right. Since the ps3 didn't do well sony probably won't want to use the name "ps4" since it would be a sequel to something that wasn't very popular.
I think "ps4" would probably be almost exactly the ps3 with an easier architecture, more ram and a slimmer design. It may even launch for $300 or $250. I'm not sure what year is likely though

"WAR is a racket. It always has been.
It is possibly the oldest, easily the most profitable, surely the most vicious. It is the only one international in scope. It is the only one in which the profits are reckoned in dollars and the losses in lives"---Maj. Gen. Smedley Butler
