Quick n dirty Amazon PS4/X1 June (it should be fully updated) in preparation for Thursday NPD
#25 PS4+TLOU
#26 PS4+Arkham Knight (Vanilla)
#27 X1+AC Unity
#53 X1+MCC
#54 X1+MCC+1TB
#70 PS4+Arkham Knight "Limited Edition Bundle"
#85 Nvidia Shield
Umm, difficult to parse, 3 PS4 SKU's =25, 26, 70, vs 3 XBO SKU's =27, 53, 54. Would seem to me to definitely lean PS4 though. I guess one way to look at it crudely would be #27 XBO cancels out #26 PS4 (basically), #54 XBO cancels out #70 PS4 (with some surplus), so that leaves #53 XBO+the amount #54 XBO outsold #70 PS4, vs #25 PS4+the amount #26 PS4 outsold #27 XBO, which is greater? Clear as mud. But yeah looks like PS4 in a fairly close month by Amazon, which anyways is consistent with recent NPD's.
One other factor thought is the PS4 Batman SKU's have been selling for a couple months and those preorders count in the months they were sold (too lazy to look up their position in past months) so this will add some more to PS4 if we are trying to equate to NPD since NPD doesn't work that way.
July so far looks quite different, but it is probably only counting one week.
#12 PS4 Arkham Knight bundle
#54 MCC XBO
#77 1TB MCC XBO
#92 Vanilla unbundled 500GB XBO (have no idea why this would even be on here, guessing some 3rd party had a sale on it)
#94 Vanilla unbundled PS4
