What I would like to see, and what I think could work, is a stand alone TES and Fallout game soon after the launch of the next gen Xbox and PlayStation, and then annual expansions for each. Each year they could release a new province for the TES base game, and a new state (or w/e) for the Fallout base game.
I wouldnt exactly like that because it would soon be like shovelware like how CoD and AC has become
MAYBE YOU SHOULDN'T BE THROWING JARS OF PEE OUT OF THE WINDOW!
