As previously reported here, NBA Live will have a constantly-updating AI (that's artificial intelligence, not The Answer) feature in the 2009 edition.
Further confirmation of this rumour comes from HoopsWorld, who elaborated on this feature with the exciting news that it will draw upon the Synergy Sports database:
"The new game is truly revolutionary as it incorporates daily updates from the Synergy Sports database, making the game more of a true to life simulator, with ultra-accurate rosters and starting lineups, and more accurate game play. Synergy powers some of the best basketball analysis tools, which are used by 20 NBA teams to review and break down players. The Synergy system will make NBA Live 09 so accurate in its depiction of players and tendencies, its impressive to think that the game will evolve throughout the season taking into account real-life streaks, injuries, roster moves and lineup changes. The system literally pulls data daily, based on the results from the last game. As a player gets better during the season, his game-play character will mirror it."
This is very exciting, as from what I've heard of this Synergy tool (mostly from Henry Abott's ravings on Truehoop) it breaks down every single play in an NBA game and assigns keywords/phrases to that play. This database gives a coach (and now NBA Live) the ability to draw up how many times say Kobe Bryant went to the basket with his left hand and missed the shot, or how many times Dwight Howard blocked Emeka Okafor's shot in a game. If this data is used correctly, it would truly bring realism to NBA Live's AI -- one of the biggest areas of complaint gamers have had historically. More to come after the official announcement (3pm Los Angeles time, today).
