I wouldn't really care if it had one or not. The only time I was excited for one was Julius Mode on DoS. Then again, considering it's a different team now, so it might be interesting if they did. Considering how heavily story-based the game seems, I'm wondering how they'd go around with it.
Hideo Kojima directed the TGS trailer, but I'm hoping it's not all cutscenes. I just want them to show the gameplay, specifically platforming bits that aren't slow and are more traditional beyond simple gaps.
