first i would love to play on an optimized less buggy engine that has amazing graphics that arent outdated right away. the difference between crysis, farcry 2 etc. and oblivion was shocking and that was only about a year. in fact bethesda could save time and money and simply use someone elses engine and adjust it for their needs. gamebryo just svcks at these types of game as oblivion, fallout 3 and new vegas and that divinity 2 game have shown. i read somewhere they they still insist on using gamebryo so it might be too late for that request....
second and more important, wait for the next gen consoles. console games look like crap today and since TES games only come out every 5 or 6 years that means if they released it next year we would be looking at 4 year old dated graphics for the next half decade. i would rather not have to play a game with archaic graphics for the next several years. and dont get me started on lack of physics and AI on consoles.
