Probably the real answer to this irritating situation is something like "all of the above". We need to remember that both the hardware and software for this are now old and obsolete. We certainly have grounds to hope that a new solution involving both hardware (graphics, browser, sim, etc) and software will be available about the time the X reaches the Design Studio. Some of that is already part of current S production. We just do not know how much it will cost, how long we must wait to upgrade and exactly what the results will be. I wager we'll see a huge map update at the same time and the Googleist (is that a word?)in me wants Waze integration including voice reporting at the same time.
Frankly, I remember when all this was state of the art. At least we'll be able to upgrade, and it will be similar to teh upgrades we all used to do with ancient desktops changing memory, chips, even motherboards. It'll just cost a bit, probably not even a huge amount except for labor.
