Brehs 2K15 next gen shows the potential 2K has if this is just the beginning of their time with the WWE license
2K16 could very well be piff if improve on what was complained about 2K15 next gen (roster, removed gametypes, more CAW slots)
Hell, 2K15 Next Gen could be in the GOAT wrestling game conversation if they dropped 2 or more huge 1GB+ patches which fixed glitches, added removed gametypes back, and opened up CAW spots (if other popular next gen games can release multiple massive updates which fix issues and add demanded features in by altering existing code without needing a complete game rewrite/redownload for users, 2K can as well)
