Imo, if there's any substance to this rumor, it's that it'll be a Vita remodel. Final version (like we had 3 of PSP), slimmer and lighter, possibly more RAM, possibly without proprietary memory.
That way they can eek out the final few million sales from Japan/Asia and a small boost from worldwide. Possibly get some of the indie devs back who jumped ship because Vita wasn't powerful enough.
It won't be a successor. And I can't see there being any market for a remote play device.
