There is a reveal trailer, but it doesn't necessarily mean we'll see Fallout 4 this year or even at E3. Bethesda could bring it up and give it a release date or say 'they aren't quite ready to talk about Fallout 4 yet after the reveal.' Part of me is hoping they'll do a Fallout 3/Fallout New Vegas Remaster for PS4/Xbox One to have the games in line with the PC (at above minimum settings).
