I have no idea what to expect besides the stuff that usually gets delayed finally getting released. Supposedly Bethesda has something big planned that is not Fallout 4 DLC. I'm not going to get my hopes up for another Elder Scrolls game ... (but that'd be really cool of them).
Looking forward to seeing what new thing From Software is cooking up.
And then I'm sure we'll see near-ready versions of No Man's Sky, Persona 5, Zelda: Legend of Double Release, etc.
