So? Not like you could play with everyone at once anyway.
Fallout 4 anyone? When is it going to be announced? That's the real rpg everyone should be excited for.
Bethesda has in no way confirmed the existence of Fallout 4, nor even given anyone reason to believe it exists at all. There is rampant speculation based on Bethesda's fairly-predictable release cycle: there's a new Elder Scrolls every 5 years or so, FO3 was in 2008, 2 years after oblivion. Incidentally, it's been five years since then, and Skyrim was released just under 2 years ago.
Bethesda, not being one of the "Big conferences" (MS, Sony, EA, Ubisoft) might not even announce a new title at E3, assuming one even exists. They've already got their hands full with Elder Scrolls Online, new Wolfenstein, and The Evil Within.
That said, Wolfenstein will be presented tomorrow at 11:40 PDT, followed by ESO at 4:40 PDT. Immediately after ESO, there's a presentation for
an unannounced title immediately after that, and The Evil Within will be presented Thursday.
Also speculation, and I'd be more convinced if it was an unannounced title between two already-announced Bethesda titles. But, if Fallout 4 is going to be announced at E3 at all, it'll probably be then. I'm assuming it's not going to be announced at E3, but would really like it to happen. When fallout 4 is eventually announced (if ever), it'll more likely be at QuakeCon (hosted by id, which is either owned by Bethesda or its parent company, ZeniMax, idr which) or something. Skyrim was announced at the Spike Video Game Awards for fuck's sake.
There are four unannounced titles total to be presented over the next 2 days - I'd say it's possible one of them is Fallout 4, but probably not likely.
Not to say I'm not hoping, though.
