Im sorry if I dont find michal pachter the most reliable source of information. He is a smart guy but damn he puts his foot in his mouth more often then not.

First article, going off one month of sales (assumed, not true numbers)
second EA is running into a chicken and the egg situation, all consolers have that at the begining of their lifecycle.
third, there wasnt anything substantial there... I mean nothing. Those werent unfulfilled preorders. It was just people saying they are interested in buying one in the future (im interested, have yet to do so)
Fourth artical disputs the first. tells the actuall sales number of 55k, not the speculative <40k
5th article didnt say much of anything, just sales numbers, that are not terribly bad.

Your not talking facts, your looking at all the fluff around the numbers in these artcles and taking in their bias.
Nintendo has two main problems, Shit marketing for the wiiU, I dont see any commercials for the damn thing, and a lack of software to get more people interested. Watchdogs is also coming out on the WiiU just so ya know.

Did you see what the ps4 games were?
Knack
Killzone
Driveclub
infamous
The witness

Destiny
Theif
