The publisher has "decided not to renew" the MBL 2K series for this year, with last year's instalment criticised for being too similar to MLB 2K12 with 'just an updated roster'.
It seems that MLB 2K references have in fact been removed from official 2K websites, signally that they have very little intention on ever bringing it back.
It coincides well with the expiration of Take-Two's licensing agreement with Major League Baseball, has it run its course December 31st. The market for baseball sports games has just shrunk to a single release this year with Sony's MLB 14 The Show, meaning there's no MLB licensed property for Xbox One it seems.
"We have decided not to renew our MLB 2K series for 2014. We are very proud of the achievements made by the MLB 2K team and look forward to their contributions to our future titles, including NBA 2K — our industry's #1 rated and #1 selling basketball franchise," 2K Games told Polygon. It's unclear whether MLB 2K's online services will continue or end.
Developer Visual Concepts is also behind 2K Sports' NBA 2K series.
