I'm carefully optimistic, the graphics are obviously pre-rendered and there is no info on the flight model nor aircraft fidelity. Yet this IS Microsoft we're talking about, and if they implement Azure right (not just being a DRM, but actually bringing the possibilities of the Azure AI as a texturer to Flight Simulator) this could be the next big thing.

And personally, I just hope there will be plenty of room for third-parties to make study sims, since there is a real shortage of those in the flight sim world.
