A:AnswerHow do you watch your movies? If it's over 4K Blue-Ray disk then get the Xbox One. I have it and it's pretty nice. However, if you're watching 4K from apps like Netflix, Amazon, and others then PS4 is a no-brainer. Plays much faster and smoother. If you also want to do 4K gaming then the PS4 pro is the ultimate recommendation.
A:AnswerI don't think PS4 1 TB gives you that 4K experience for that you need to buy PS4 Pro which has better performance and higher configured processor inbuilt.
Also, 4k makes no sense if your TV is not a 4k and the game you are playing is not 4k. Check about that before you look to upgrade or buy a PS4 pro.
A:AnswerWith issues supplying certain parts to build consoles along with the inevitable bot buyouts keeps things slim. Every month they have some shipments come in about 2-4 weeks, but with some suppliers seeing a month or two before restocks. It should get better as time goes on and eventually you could find one in store.
