This is Japan's E3, you can't just show nothing new, SuperBot.
Key point is that it's JAPAN'S E3, not ours. This means the entire show is geared towards the Japanese audience, not us. Bear in mind, for months it looked like this game wasn't going to get a release over there, so TGS was just showcasing the game for them since it's relatively new for them. THAT'S why there were no reveals.
Calm down and think for a moment.
Snake or Cloud would have not only made the Japanese happy but also satisfy us.
