25.3m as of end of June.
My projections...
End of September: 28.8m (+3.5m)
End of December: 35.8m (+7.0m)
End of March: 38.3m (+2.5m)
I really really wants to see Sony shipping over 40m this FY but I guess they will fall just a bit ahead 38m.
We shall see but who knows. Sony has some nice bundles and marketing deals. I think Destiny bundle in sept will prove to be fruitful for them. And I think the MGSV bundles in JPN and EU can provide a small boost.
But the holiday season coupled with an inevitable COD and Battlefront bundle along with the other deals retailers do could be HUGE.
