Personally I would like to see some sort of system that uses a form of player tracking, perhaps based on what buildings/dungeons the player is approaching or if the player has a quest there. The game could then attempt to detect and "predict" what doors the player will activate, effectively preloading the interior cell and all of the objects within, resulting in the seamless opening of the door ( the door would physically OPEN) and entering of the room with no annoying loading screen - a truly open world. I think this would dramatically improve the realism and immersion of the Elder Scrolls experience.
What do you guys think? Good idea or is this just a forlorn fantasy...
