I'd guess that Sony will give some and MS will not. They only like to give numbers when they can put them in a good light.

Just gonna leave this here...

I think the Xbox One will fare better than a lot of people think it will. Master Chief Collection alone will probably be the biggest hit this holiday season, and should move plenty of units.

I doubt it does as well as the PS4, still. Closer than what it has been these last few months, but I still think that the PS4 will have around 1.5x as many sales.

If PS4 has already made it 2:1 with Xbox then why do people see that ratio shrinking or staying the same now with Destinie set to dominate on PS4 (see Watchdogs)

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.

september is going to be a big month for both consoles, i'd say 220-250k ww for xbox one, 380-440k ww for ps4.

You mean for US only, or what?  The global sales are going to be a lot higher than that.

X1s best hope is ps4 sold out lacking stock just like last xmas.

worldwide, hence ww.

but based on what metric are you saying it'll be a lot higher?, hopefully not destiny preorders.

Given that PS4 sold 664k in June (maybe more after VGC adjusts) then yeah it'll be a lot higher.  440k would be a big decline, so I don't get it.  Are you talking about weekly sales?
