This one is going to be an entirely new type of game for them, so I'm ok with the graphics and engine being the same. They should be supporting it for a while too, so who knows what'll be introduced. For this one I'll be mostly playing at the same time as my brothers, since we all have computers capable of playing it. We haven't had a truly co-op game in YEARS, so that already is going to be immense fun for me and something I've been longing for.
The next main series game, they should have a ridiculous amount of money for, so I think we'll see such changes then

. I think we'll have a better idea after the new Elder Scrolls game comes out.
