I was there on Saturday. Got there around 10h30 and left at 12h00 due to the minimal attractions and lack of control over the exhibitions.
Good luck to you if you wanted to try your luck at GT6 with the Logitech G27.
At least it's a start though.
I wish I could've been there just for the hell of it, but not so much FOMO from what I've heard from my mates and your guys reviews. Excited to see what they can pull out the hat next year though, I'm sure it will be a lot better!
