Bethesda MADE a whole new engine for this game... we honestly could be looking at a completely different game than ever before.
I mean i know that the previous games are what these will be based off of, but visually and even gameplay wise we literally have no idea whats in store for us
I for one have said out loud this in my posts.
For one it means they can build it to suit what ever needs they have and make the limitations of the engine be what they don't need to have or what they cannot make.
This discussion is pointless. Unless we see a screenshot, we cannot say ANYTHING about the engine.
We can. Without doubt it will support open world. They are building the engine for Skyrim. We can also say that there's reason that they decided to make new engine. They wanted to get rid of the crashing glitches their old engine was plagued with, from Morrowind to New Vegas or they had ran into the limits of what the engine can do and it was getting in the way of what they wanted to do.
