will Microsoft release an "xbox OS" for the ROG ALLY X?

It already has an optimized OS

You should not be running anything at 120hz on a portable device. Your battery will make a flood look tame how fast it empties. I'm sure some games will but it's not a good idea

This is a Windows handheld, and it plays windows games, and only PlayAnywhere games would be playable from your Xbox library

at this time there is no indication that would happen

you could play them through cloud gaming, but these games cannot function natively on a PC which is what this is.

While Xbox shares many of the same technologies, it contains strong digital rights management, as well as a custom architecture that is not compatible with the PC

It still doesn't work. On my rog ally it doesn't update and it stay on updating with 0% progress

The handheld is just a rog ally x

And unless it's confirmed on news.xbox.com

I would take things with a grain of salt as the galaxy black xbox didn't meet all the leaked info

For example bluetooth was still missing and there is more then one model of galaxy black which started the uproar about a lack of a disk drive
