Shipped =/= sold through? Could be the discrepancy.
AMD said "almost 30 million"
Take Two said "exceeds 29 million"
and Ubisoft saying "over 28 million"
I think there is a general consensus that the combined sales Ps4/XB1 were not at 30 million by the end of 2014. This rules out XB1 sold through being at 11.5M. Because 18.5 + 11.5 is 30million and reports are saying it's under that.
They can't be referring to sold through anyway because Microsoft has only updated shipped or sold-in. Microsoft investors don't even know the split. This would also be a shift seeing as how IDG has normally reported shipped numbers. Unless I'm missing something. Does anyone know for a FACT that they are using sold-through?
Also based on Sony's report, we know that they shipped 19.9M at the end of 2014. Microsoft probably hit the 10m shipped milestone by the end of 2014.
But this lines up with the prediction me and a few others had about XB1. But this is only speculation.
But the 2:1 is all but confirmed at this point.
None of this explains why Ubisoft is so low.
