How much will PS4 & XB1 sell during Sep-Dec 2014?

[ICStats]

In 2007, Halo 3 boosted the 360 to 4.8M in Sep-Dec period. I don't think Halo Master Chief Collection will match that in this market.  The 360 had a $299 version, and was in a better competititive position.  This year PS4 will be having part of those sales.
