Sony decided not make any PS4s with a 4K Blu-ray movie player drive included therefore getting an XBox One X is really good value for a 4K Blu-ray Player and higher spec video game console in one.
Most standalone single function 4K blu-ray players retail for around $300 - $500 anyway.
Games I have already bought for it are Halo MC Collection, Rise of the Tomb Raider (have it on PC, PS4 and XB1 now), Cuphead, and Sunset Overdrive.
Although the XBox One X is not backwards compatible with some of the XBox 360 games I have.
Tales of Vesperia is a notable popular one that is still not compatible with it yet.
Others made by companies like Konami are not likely to get backwards compatibility either.
