I think the fact that Microsoft allowed the delay of Halo by a year and Spencer has even said that you don't need to upgrade to an Xbox Series X right away demonstrates that they are focusing on a longer game. Once Bethesda games and their other studios start pushing content out, that's when you're going to see a bigger push for Xbox Series hardware.
They're mainly trying to push the ecosystem, which incorporates Xbox Series hardware, PC, phones, and soon things like TVs. The game plan is Game Pass. Once you see Starfield and Elder Scrolls VI releasing on that service for no additional cost... it's going to make waves.
It's just a different strategy than Sony who is going to rely more solely on Playstation hardware.
Well, that's not true. Both Sony and Microsoft react to each other. Or, I guess you're going to try to argue that Sony didn't create trophies as a response to achievements (just as one example)? Also, see below where I'll refer to Sony's stance on backwards compatibility in 2017 (with current leadership).
Also, Game Pass isn't game streaming. There is no streaming involved with Game Pass.
Microsoft's game streaming is xCloud/Xbox Cloud Gaming, but that tech has been in the works for years and years and is a core part of Microsoft's business strategy as a whole using Azure. I believe the video that I saw where its tech was first being demonstrated was in 2014, but at the time Microsoft said that streaming wasn't viable for gaming yet and was focused on continuing to develop it until the time came to where they thought it could be viable.
I don't think that's shifting goalposts when the current leadership downplayed backwards compatibility - basically at the time deemed it unimportant and not worth it.
