Well since we don't have this thread, I thought it would be nice to discuss various gameplay mechanics.
With the Turtles having weapons in their hands, it looks like they won't be able to do standard throws. I don't know of any fighting games that have throws when the characters uses hand weapons.
I would like the opportunity to grab someone and throw them at the wasp/hornets' nest. I would like to throw someone in range of the "gator" leaping up so it would grab them. Throws do help a game along. You have throws in Smash Brawl, so what could be in store gameplay wise? Plus it seems that you can "recover" (looking at the NYC rooftop stage, the sides of the buildings below the platforms seem to be "wall huggable" and I could see ninja turtles leaping around trying to get back to the top level.
I'm enthusiastic about the game and can't wait to see what is newly revealed at Comic Con in July.
