Bethesda has announced bran new technology, and a new engine...
Does this mean we will have to say Adios to our faithful friend that kept Oblivion alive for 4 years?
Will they improve the engine - Or replace it?
Morrowind had an construction set and when Oblivion was developed they built a brand new engine for it . . . . and Oblivion still had an editor.
I don't see any reason to believe that TES V having a brand new engine means it won't have an editor.
At this point the conversation is just going in circles so I think it's time to give this a rest until Bethesda has definitely said that TES V will or will not have an editor.
(With FO3 Bethesda didn't confirm an editor until after the game had been released, before that they told us they'd look in to it after developement was over.)
