Ironic that you chose the Apple TV. There's a bit of nuance, and the 3rd gen was $149, not $129 (the latter is Wifi only, when the first two were Wifi+Ethernet).

They then bumped UP the 3rd gen: $249 (+$100) and $199 (+$70).

And the 4th gen has only one option, at $299.

So we've not only "not dropped" prices on the 4K Apple TV, but they've gone up forty per cent.
