GR: Filling this feature is more difficult than it looks. Why? Because of rumors. So many that we can swim through them like Scrooge McDuck. (Except we aren't rich.) How unexpectedly would our eyes explode if we were to see Mass Effect 4, Halo 5, Killer Instinct, a new Zelda for Wii U, and the ever-fabled The Last Guardian? For sure, we anticipate them feverishly, but who knows whether we can truly expect them to be show at E3 2013. What we note below is what we're fairly to very sure will be shown... we can't wait.
