Okay, so Nintendo's 3DS looks badass, there's a new Zelda for the Wii, and BioWare's latest CG trailer for The Old Republic makes me sadder than ever that the game's an MMO instead of another great single-player RPG. But honestly, nothing at this year's E3 has me even half as excited as this brief glimpse at Valve's Portal 2, which is set to hit sometime in 2011. Cannot. Wait.
