I’m a little late in posting this, but a new official roster update is now available for NBA 2K12. The latest update includes 2012 All-Star rosters (though the Rookies and Sophomores teams remain unchanged due to the new format the NBA used this year), the 2012 All-Star jerseys are now the default home and away jerseys for the East and West All-Stars and a big online data update has added Orlando’s All-Star court, though the menu and overlay text still refers to the Staples Center and Los Angeles.
The updates will be downloaded automatically as long as your PC, Xbox 360 or PlayStation is connected to the Internet. Note that you will need to use the Reset Roster function under the Options menu to get the new rosters to show up. For PC users who would like to update their rosters and online data manually, I’ve updated the package with the latest files here.
