Good list. I'm on board with everything but the RTwP. That would take a pretty big change to the engine.
The PoE engine has both Turn and Real Time modes. Hopefully BG 4 will use it and then we can get painted backgrounds as well.
(but the PoE engine needs to be tweaked -- I have a decent gaming laptop but the engine still felt unresponsive much of the time. "No, I said move now, not half a second from now . . .")
