On last night's Jimmy Fallon, the first footage of Battlefield 3 on Playstation 3 was shown off. There was only around two minutes of gameplay, but the differences between the console and PC versions were readily apparent. Two people from EA Games played through a short segment that we have seen before. The controller was then handed over to Jimmy to play around with. Jimmy pulled out a knife when trying to shoot a guy 30 feet away, he kept his cool though and eventually shot the cover that the guy was hiding behind.
Last picture shows up the differences between pre-alpha and alpha development(sat. dishes, greasy arm).
