Sorry to bump an old thread, just got some news on the grapevine.
Sequel/new game from Tango post The Evil Within will not feature at E3. The team is most likely targeting TGS2016 at the moment it seems. Planning stage finished a few months back and now in the process of early to mid development.
Regarding Bethesda as a whole, I'm hearing talks of Skyrim coming this E3 as a possible remaster with mods for consoles.
