300-400k sounds about right given the bottom of the barrel pricing and freebies MS was throwing in with the system, can't imagine they made any money in November, and after paying publishers for all those free games, they probably actually lost money, but they did manage to close the gap by a 3rd in the US, give or take. I'd wager Sony made more money in November on console sales than MS did, most of the big releases still sold more on the PS4, minus bundling, COD, and Madden.
People thinking MS will wipe out the gap completely by February, lol. January and February will be dead months, if anything in the first half of the year is going to move a needle, it'll be Bloodborne when it hits, and more so in Japan than in the US I would think.
It'll be interesting to see if they stick at $350 come January or raise back up to $400. If they settle at $350, I expect to see Sony announce a cut to $350 around E3, probably not before.
