Right now the PS4 version is way further along than the PS3 version in updates. The PS3 version was always a bit limited in what it was capable of and they realized it wasn't going to be able to keep up forever.

Also the PS4 lobbies were always much larger.

So it's more of a technical problem than a software one.
