BioShock Infinite's Heavy Hitters will hit you heavily

This is sort of a new trailer for BioShock Infinite. There's about 20 seconds of game footage and like 2 minutes of nerds talking about robot George Washington or something. It looks awesome. I never did play BioShock 2 but I loved the first one. I've been told that the story for 2 wasn't as good, but the fighting mechanics were better. I think I might just skip it and go straight to Infinite.
