Since it seems half of the Sony conference will be dedicated to Morpheus, and since Bethesda will hold a conference for the very first time, I'll go with Bethesda.
Fallout 4, Doom, maybe more Wolfenstein, Dishonored 2 (one can dream)... That'd be swell.
I also highly anticipate Nintendo's reveals. Still hoping for a new Metroid game.
Just because you have an opinion doesn't mean you are necessarily right.
