This is simply false the PS4 is at 6 million consoles sold in under 4 months[1]. While the PS3 had sold less than that in 7 months[2]. While I'm not going to double check all the numbers, the PS4 is supposed to be the fastest selling console to date.

And it's just entirely bullshit to try to compare total consoles of all types sold in a particular months, considering so many variables.
