I'm pretty sure the original Black Ops got a ton of crap when it was first announced and still went on to sell like hotcakes.
Seems to get more and more negative press every year but they repeatedly still broke sales records so although there could be a chance of a dip in sales i still think it will sell like hotcakes again. The sales statistics make for an
interesting read (stats only listed up until November 1st, 2015).
