Pre-recorded, yes, but continuously being updated. How many sequences can be recorded and played back is the question, and will it overwrite older sequences for new ones or will it just stop recording once the allowed memory is full?
Still, I'd love to see it in a game like NBA 2K or Live. Imagine if it recorded human players then had the computer team throw that at the gamer. Play against the computer while it played a Kobe as if he were slashing and attacking as if a human were on the sticks.
That's what will eventually happen. Hopefully they will allow gamers to record their own sequences as well and upload them to share with other users, with categories for specific players and player-types.
At the Elite 11 community day, the build we played allowed you to record sequences in one on one mode with a simple click of the right stick. Elite 11 was supposed to have REAL AI. But it was a small form, where the developers could record sequences that real life nba players have done, for specific moves, and such. I don't think they were able to record the user during a game and play it back later, though.
