The Xbox Wire post announcing the new Xbox app game aggregation only mentions that you'll be able to "launch games from Xbox, Game Pass, Battle.net, and other leading PC storefronts," initially leaving Steam with a big question mark beside it.

The update aggregates all titles across supported PC gaming storefronts to turn the Xbox App into a universal launcher. This is especially handy for people who buy games on Steam,

Microsoft is starting to test its new aggregated gaming library in its Xbox PC app on Windows. Xbox Insiders will now be able to see their Steam and Battle.net games all within the Xbox app — making it a single launcher for most installed PC games.

All versions of the Meta Quest 3S (Xbox Edition or not) support the best Meta Quest games. You can also stream games to the headset through Xbox Cloud Gaming. The headset does not support playing Xbox games natively, which makes sense considering it is not an Xbox console.

The limited edition Quest headset is basically a black Quest with an Xbox controller and a fancy head strap. Will Microsoft be planning more with this Xbox-to-VR overlap beyond GamePass?

The main difference is the black-and-green Xbox look. The $400 bundle includes three months of Meta Horizon+ and Xbox Game Pass Ultimate.
