Heh. I posted in a different thread a few days ago, talking with Cosmic; it's really hard to make clear statements when things were as close as they were last month. We didn't see anything in our stores to reflect the XB1 winning last month; and considering how much larger the percentages are for GS, that makes sense.
When I check numbers in various districts, the PS4 is consistently the better seller, on a week/week basis. That's been pretty consistent outside of specific outliers, from the Best Buy angle. It's not a tremendous gap, but it is still generally selling better. How that reflects on the larger spectrum? (shrug)
The White XB1 didn't really accelerate things for us. Sells to those looking for a different color, but it's not like they made a big deal out of it, like with the Destiny PS4s last year. But again, that's Best Buy. I can't speak for walmart or GS impact.
