is amazon haveing trouble with stock of PS4s? Trying to sell out and wait on bundles? what gives.
PS4 has several SKUs on Amazon: Uncharted bundle, Destiny bundle, gold, slim, old model, pro, I think there's a PSVR bundle. All of these dilute sales rankings, I imagine. The same could be said for the various SKUs for X1.
That could explain why PS4s have seemingly fallen in the top 100.
