The most logical reasons off the top of my head as to why Activision would ignore the WiiU version:
1. They want to increase the userbase of the Xbone and PS4 consoles more than the WiiU, since they sell more software there
2. They put a huge emphasis on DLC, something the WiiU versions of their games don't support. If they want to maximize their profits, they want people buying a console version other than the WiiU version
