Microsoft has altered its statement on its policy for Xbox Play Anywhere titles, suggesting that not all future Microsoft Studios games will be playable across both PC and Xbox, as originally stated.
In the original statement (viewable on Wayback Machine), Yusuf Mehdi, CVP of Microsoft's Windows and Devices Group, explained: "Every new title published from Microsoft Studios will support Xbox Play Anywhere and will be easily accessible in the Windows Store."
The revised statement, however, states: "Every new title published from Microsoft Studios that we showed onstage at E3 this year [emphasis added] will support Xbox Play Anywhere and will be easily accessible in the Windows Store."
The new wording suggests that Microsoft doesn't want to commit to all future Microsoft Studios-published games being playable across both PC and Xbox, meaning we'll have to wait and see whether future games in the Halo or Forza Motorsport series could come to PC.
Multiple games have already been confirmed for Xbox Play Anywhere, however, including Forza Horizon 3, Scalebound, Sea of Thieves, Halo Wars 2 and Gears of War 4. The first game to be supported, ReCore, launches on September 13.
