As per the official 2K Support Twitter account, the NBA 2K19 servers will be shut down on December 31st, 2020. After that point, all online content will be unavailable. This includes Play Now Online, MyTEAM, and the entirety of MyCAREER and its connected modes. Any Virtual Currency and MT you have will also be lost, and in-game roster sharing will no longer be possible.
This falls in line with 2K’s policy of providing online support for 27 months, adopted after the NBA 2K14 server shutdown resulted in controversy. Interestingly, the NBA 2K18 servers were kept online for an additional three weeks, before being shut down earlier this year on January 18th.
Since December 31st is only a little over a week away, I’d advise you to wrap up any business before the NBA 2K19 servers are gone. This includes aiming for any Trophies/Achievements in the online modes, completing a season in MyCAREER, and playing with your favourite MyTEAM cards. With roster sharing also disappearing once the servers are gone, I’d also recommend that you download any rosters you want while you still can. This includes projects such as the Classic Seasons rosters by Stildo33 and company.
