Microsoft seems to have subtly changed the wording of a recent announcement regarding its "Play Anywhere" cross-platform Xbox initative to state that all Microsoft Studios titles shown at E3 this year will be playable on both Windows 10 and Xbox One.
That's notable because, as YouTuber The Red Dragon points out, a previous version of the same announcement (viewable via the Internet Archive's Wayback Machine) stated simply that every new title published from Microsoft Studios would support Play Anywhere and thus be playable cross-platform.
The subtle rewording limits the scope of what seemed, a few weeks ago, like a very ambitious program. At the time, that program appeared to be a cornerstone of Microsoft's strategy to expand its Xbox video game ecosystem beyond the constraints of the console.
Plus, there's at least one Microsoft Studios-published Xbox One game in the works that's not currently part of the Play Anywhere program -- Capcom's upcoming Dead Rising 4. The game was announced at Microsoft's E3 conference last month, so presumably (as NeoGAF points out) it's a glaring exception to both versions of the afore-mentioned Play Anywhere announcement.
