Maybe had activision bothered to let the public know this was the supposed best version and didn't just throw it out with no advertising or any form of nod at the Wii U version it would have sold better.
This. Offering a preorder for nuke town and than pulling it with a week prior to launch and to this day still not publicly address the situation sucks. The other issue is that it released later (yes a week but) millions of people were not going to cancel preorders and buy a 350.00 system with lots of question marks prior to launch for COD.
Activision and Nintendo decided that they would not promote it at all. And they expected what a million copies sold??? I agree that it deserves better sales but that hasn't happened and now with no expansion pack and the lack of support they are going forward with the game will drive sales down lower.
