The entire thread is one person's delayed twitch-reaction to the Kotaku report.
I can think of a few valid arguments that can excuse the poor performance, such as the small install base and absence of demographic, but all of them would require the admission of the game not doing so well, and simply not attaching to hardware sales. However, as you pointed out, the refusal to concede to such simple facts and attempts to spin those numbers into something GOOD or PROMISING is indeed baffling. It's almost as if vocalizing these spins on a public forum would somehow affect the implications BLOPS2's performance will have on series' future on Wii U.
COD on the Wii U will continue to lag behind the other versions, the only thing people should worry about is whether the install base can cross the threshold of online activity that insures anyone to easily connect to matches on any mode.
