Yup, Microsoft even said, if I'm not mistaken, that they don't necessarily want you to buy a new Xbox. Gamepass is their big feature.
It was already an incredible value, now add in day 1 access to any Bethesda title, and in the winter they're adding EA Access to Gamepass for no additional charge.
And MS just released a Beta to stream games from your console to your phone, on top of already having unveiled access to xCloud a week ago.
