Do you mean:
A) one entirely long gameplay animation that's executable in game?
B) one entirely long cut scene animation?
I'm saying it's entirely a cut scene because that type of smoothness has never been seen in Live gameplay. Also take notice of the other players in the background. The smoothness is usually only apparent during EA cut scenes. Even with what little Live14 gameplay footage we've seen, Live14 seemingly will have the same classic EA robotic animation.
I went back to youtube and took a look at all prior Live releases. There's a quality to Live's animation that's a trademark to both LIVE and MADDEN's franchises ever since the PS3/XBOX360 era hit.
