NBA Live Developer Fernando has posted an update on the status of the rosters for NBA Live 14 here in the Forum. It appears as though further issues have arisen, which have prevented the previously mentioned update from being pushed through. Although there is currently no timetable for a new roster update, the team is apparently working on those issues and are hoping to get a new update pushed through as soon as they possibly can.
In the meantime, NBA Live 14 has still been receiving other content updates, including new BIG Moments and LIVE Season games, as well as new packs and player cards in Ultimate Team. According to Fernando, the update system will be configured differently for NBA Live 15, so they don’t anticipate having similar issues with the game when it is released later this year.
