The PC version of Final Fantasy XV will be coming in early 2018 alongside all of the DLC. In terms of improvements it will bring with it a first-person mode, support for 4K resolutions and HDR 10, as well as graphical optionss that you can tweak to support resolutions up to a rather ridiculous 8K!
So if you're wondering what sort of PC you'll even need in order to run FFXV, wonder no more as the developers have now released the official PC system requirements via the Windows Store. They are unfortunately a bit shorter and less detailed than the ones Bethesda or Ubisoft like to release, but it should still give you a good idea of what to expect. Have a look:

DirectX: Version 11
Memory: 8GB RAM
Processor: Intel Core i5-2400 (3.15ghz) or AMD FX-6100 (3.3ghz) CPU

If you would like to learn a little bit more about Final Fantasy XV and all of the bonus content, you should head on over to Steam. And finally, allow me to leave you with a recent gameplay trailer, just so you know what sort of visuals your PC will be sweating to achieve. Enjoy!
