A:AnswerThe PS Pro has more memory therefore games are not offered with this system from what I could determine. I was told that the PS4 Pro was a must if you plan on getting the new 4K TV's. Also there aren't many games developed yet to compliment the 4K TV. So if you have the regular TV you will be ok with the regular PS4 system.
A:AnswerWhen I had purchased the games were in the cart and arrived well at home separately from the system tho. Best would be to call and assure this if anything. Good luck
A:AnswerNo, It is not backwards compatible. I have a PS3 with a ton of games and cannot play any of them on the PS4. There were a couple of games that came out around the original release date that you could get PS4 compatible game copies for, but that was it.
