Guys, this will not be a subscription service. The only subscription you'll need is for your internet at whatever speed you want to be able to stream the data. There are several other games coming online that use streaming of major amounts of assets like MSFS 2020 is going to do which also aren't subscription-based business models, so Microsoft won't be doing anything new. In fact, one game I've been part of early access for, Star Citizen (
https://robertsspaceindustries.com/) streams all of its assets in and out and does a lot of server-side computing to make the experience much more immersive because the servers can crunch so much more raw data than most PCs can. The base game takes about 55GB on your drive. That's 1/10th of say GTA 5 (over 500GB drive) and about 20% of my current P3D installation (~350GB).
I know there are people who will not believe it, but bandwidth is still pretty cheap, especially for companies like Microsoft who buy it in massive amounts. The only place we have bandwidth limitations today is over wireless connections. There is still plenty of bandwidth available via "wired" connections and it's only expanding. "Cloud Computing" costs are plummeting to the point that individuals can afford to have their own AWS subscription.
