He said that the whole set the internet on fire was a misquote but I still don't believe this.
Square is still busy with the DLC and PC port. The core team of CB III have also moved on to Dawntrail and the balance to Rebirth. I doubt an Xbox port is at the top of their priority list, especially since Square don't seem to be keen on Game Pass deals anymore.
If it comes then great, a port of a game that will be close to 3 years old at that point comes to a platform that's going third-party anyway. Don't see it attracting anyone to Xbox though. Social media points and not much else will follow.
