Rather than purely streaming frames, you could push a frontend client in e.g. webgl + wasm on demand, cache artifacts locally, and send view-independent texture/mesh streams down. Doing so is technically more complex than having a rigid client/server split, but if they start with full streaming they can progressively make the client more intelligent, without being burdened with any specific hardware/client infra choices. It's also easy to port edge-rendered games to many platforms. It makes sense for MS to ally with Sony and shift their effort to cloud before both the Xbox and PlayStation are little more than rich web clients.
