I'm going to GC, that's why. I think E3 overall was a good show since you got a competitive price, confirmed 2013 release, announcements of some big games like FFXV, KH3, Arkham Origins and some other stuff like The Order and Destiny's gameplay reveal. Though, I'm comfortable saying SCE is going to have a better showing at GC than at E3. I also realise the joke in that since they only showed one new game at E3 so I understand the bar isn't exactly high.
Edit:
On the note of Arkham Origins, can you imagine the next generation Batman game? I was thinking about this a little while back, but I'm excited for that more than anything else. I don't even know why. It must be that Deadshot trailer for Origins. Batman Next Gen will be bloody amazing. Hell, they should try and lead into something like Batman: Justice League.
