I don't suspect that the Xbox One X will get Dolby Vision, and that just comes from the fact that the Xbox One S could've supported it too, and Microsoft has never even announced support for that console variant. Microsoft could even charge a fee to support the development and licensing costs like what they do with the Dolby Atmos for Headphones software for Xbox and Windows 10 (I think it's $15?).
Also, the Xbox One isn't a very good 4K player anyway. It's too noisy. I mentioned it in another thread, but just go to the store and lift up some of the UHD players. You'll probably be surprised at how much they weigh when you consider that they're just a disc drive, a control board and an I/O board. The latter two boards aren't even that big, and said boxes actually have a ton of dead space. For example, here's the
internals of the Oppo BDP-203. It doesn't look that fancy compared to the innards of the Xbox One, which includes heftier heatsinks and such, and even with all that, the Oppo UHD player weighs around 10 pounds. These UHD players are built to contain disc vibration noises, which the Xbox One just doesn't do. I originally upgraded to the Xbox One S just as a UHD player, but I kept hearing the disc while watching Sicario, which was unacceptable to me. (The disc also would freeze randomly at spots, but it didn't on a dedicated UHD player.)
Yup don't count on it. HDR-10 is an open standard. Yes Dolby Vision is better quality but then you also have licensing fees associated with it. Especially since more TV's support HDR-10 for that reason as well no reason to expect them to add it.
Last I read, the licensing fees really aren't that much on a per-item basis. However, when you're selling millions of units, even paying one dollar per unit equates to millions of dollars spent in just licensing. Keep in mind that these companies have to implement their own software to handle it as most don't have hardware solutions. So, they've also got to spend time developing and debugging the software implementation. Also, if most people don't use it, it may not be worthwhile at that point.
Sony sold their X1 Extreme-based UHD TVs that they would be getting Dolby Vision, but at this point, they still haven't released it via a firmware update. They recently showed Forbes a demo of it working, and the reviewer had great things to say; however, they also stated that they'd have more information on a release date in December. (Some people are assuming a March '18 release date.) I own a 930e, and I can't even use Dolby Vision until they release that update.
