That's not going to happen. The main benefit of developing natively for windows is that the game should pretty much compile for Xbox straight away, with some minimal changes to the code. The PC build is almost a byproduct here. I don't personally see devs making a linux-but-not-really version for Windows if that cuts them off having a "free" xbox version. And from financial point of view having a Linux vs Xbox version is almost a non-starter, unless you're targeting some hyper-nieche.
