A lot of what you listed is server limitations so dropping PS3 will have no effect.
PS3 was the bogeyman for players with every design decision blamed on that.
You wont get more customisation, maybe slightly more elaborate hairstyles and tattoos but there's going to be no more sliders. AuRa wont be changed either: they look like SE want them too. There's also the issue that changing models could piss a lot of players off who like the current ones.
Zones might get prettier and slightly bigger but it's not going to change the game in a meaningful way.
