To clarify for all of you beautiful people.
A major outlet visited Microsoft this week to take a look at Scorpio and its specs, using Forza Motorsport 7 as a showcase.
I've had the information about FM7 being a 4K "showcase" for a while, but it wasn't until a friend of a friend of a friend of a writer at this particular outlet (no prizes for guessing who) leaked the big reveal to me that I considered it confirmed. It made previous information I had make more sense, combined with info I got from what's happening with the Forza guys, etc. Expect a deluge of coverage next week.
The fact MS is showing off Forza and Scorpio now potentially bodes well for E3, hopefully they're going to give us a better idea of what their games line-up will look like in 2018 and beyond, but they're prob going to be cautious with how far out they go, due to the whole Scalebound thing. I think they're aware of the narrative surrounding how their line-up looks like compared to Sony's.
We generally have good info on Microsoft's internal happenings from years and years covering Windows, Surface, Lumia (RIP) and whatnot, as tech press rather than games press.
Cheers
