When Valve said that they had a surprise for E3....wow I wasn't expecting that! Sony really closed that out well. GT5, Steam (and Portal 2), Twisted Metal 3 (though I've never played the first two, the audience sure seemed pumped up).
They really emphasized Move, to the surprise of nobody. It looks like it has potential, if the 1:1 isn't a joke, but nothing truly wowed me. Until then it's just another Wii rip-off competitor, no matter what they force Butler to say.
Also I was surprised by how little MGS was mentioned, unless I missed something. Even Nintendo seemed to give Kojima more screen time. :/
