According to NPD, NBA 2K14 is the number one selling sports title on next-gen consoles and was the number four best-selling next-gen game overall.
Below is a statement from 2K.
"Earlier this year we promised that NBA 2K14 would be our biggest and best NBA 2K experience yet, and today we’re thrilled to see fans agree, as NBA 2K14 is now the #1 selling sports game on next-gen consoles,” said Jason Argent, SVP of Basketball Operations for 2K. “NBA 2K14 for PlayStation 4 and Xbox One distinguished itself by providing an entirely new experience designed specifically for next-gen platforms, featuring all-new game modes distinct from the current-gen version of NBA 2K14. We partnered with the King of Basketball, LeBron James, as our cover athlete and delivered an unprecedented level of realism, making NBA 2K14 a showcase for the potential of next-gen gaming."
