A:AnswerNo 4K I'm affraid. The HDR is mostly for streaming and some compatible games. If you want the 4K experience the PS4 Pro is the way to go. Just remember, this is limited time console so when it's gone its gone.
A:AnswerIt comes with 1 steel black controller so we picked up a metallic copper and gold on the side. It complements it very well and both were on sale during the "Days of Play" sale going on until 6/17/19. :) Copper was sold out for weeks I heard at my local store so we purchased one to be shipped instead from best buy.
A:AnswerTheres no "charging dock" for the ps4, just the upright dock. The console has 2 USB ports in front that you plug in docks to charge your controllers and accessories. And there's a pretty cool playstation dock that also has a controller docking station built into it. But the ps4 itself gets plugged into the wall directly, and doesn't have a "charging" dock
A:AnswerI believe Bestbuy will give you a $100 BB giftcard to use on whatever, so you could use towards the purchase of the PS4. You will need to check with Bestbuy for actual giftcard amount.
A:AnswerI don't think so. While it should be fine up to about 20 feet, any longer and you will probably have issues and disconnects. The maximum theoretical is 60, but this is without interference which your setup has (walls, furniture, etc.)
