In his Discord, Jez was more chatty:

All Xbox first-party games coming to PlayStation, even Forza, Halo
Xbox will be more Steam-like in the future
Affordable prices, sales, more open for devs
Future Xbox-Hardware gonna be for fans who want it
Xbox hardware will be niche like Steam Deck
Next Xbox will side-load Steam
« I don't think they expect to ever grow in hardware »
he said « Nobody wanted to give Xbox a chance, so this is what they get with a Sony monopoly »
