This puts the official 7th Gen numbers at 87.4m for PS3 and 84m for 360.
Of course the last official 360 numbers were in 2014, so it could have still ended ahead of PS3. The ball is in Microsoft's court.
They would have probably been singing from rooftops if that happened (Microsoft). I think it's a better bet to assume otherwise (particularly when plenty of sources called this years ago). It also makes sense when you align the systems, as the PS3 sold more each year it was out (how that gap closed at all).
