I have great news, about a week ago, not only did Bethesda confirm that this rumor is true, but they also confirmed they are not using the same game engine (Gamebryo) they used in Morrowind, Oblivion, and Fallout 3. So it will be very interesting to see how great they do in the next game with the new engine. What engine they are going to use has not yet been announced, they just said it is an "all new engine"
