I don't understand the mentality of excluding Nintendo here... they are all console manufacturers, they all are direct competitors, just with different products....
Some people do some crazy mental gymnastics here.
By my estimation the prevailing mentality on Vgchartz, historically and currently, is to not consider Nintendo a direct competitor to MS and Sony. Again and again. Through success and failure. I do not ascribed to this line of thinking, but feel it's quite pervasive.
