I saw that footage on screwattack a while ago. Its worth looking for. I was worried about the game until I saw it. It plays nearly identical to the first game, which is both good and bad. Some of the context sensitive kills look decent but it looks like the only thing they added to the series thats of any significance. The city they were in looked very nice though.
This is still my most anticipated game for next year. Even a shameless knock off of the original is good enough for me.
