It is incredible that the Xbox One sold the most only in the 6 year and outsold the PS3 by 600k+ in 1 month.
I think that the PS4 will be able to surpass Xbox 360's sales but it will be hard to surpass Wii's sales.
Well, it is worth pointing out that, at least for PlayStation & Xbox, November has been growing as a sales month in both absolute and relative terms. I made a thread about this a couple of months ago. The PS4 may or may not have a record-setting November (it will for PS systems only, but maybe not for all consoles), but December will favor older systems in a Top 15 December performances chart. I haven't made such a chart yet, though.
