: According to MS's Shannon Loftis, "Any games we're making that we're
: launching in the Scorpio time frame, we're making sure they can natively
: render at 4K." Seeing as Halo 6 likely won't be launching until 2018,
: that entails that Halo 6 will run at native 4K resolution on Scorpio.

Well, she did "can" instead of "will." Here's an excerpt from a Eurogamer interview with MS's Albert Penello:

So as far as you're concerned, Microsoft will not dictate to developers that they render games in 4K? That, if they wish, they can have their game run at, say, 60 frames per second and not render natively at 4K?

Albert Penello: Yeah. We had to pick a number. Why did you choose six teraflops? Why did you choose 384Gb/s in memory bandwidth? What's the point of those numbers? The point of those numbers was to deliver Xbox One-quality games in 4K. That's the point of those numbers. But we're not going to dictate to developers that that's how they have to use that power.

So, Halo 6 might not be in 4K at all on Scorpio, but rather target a constant 1080p60, hopefully with added details and overall better graphics than Halo 5 or the basic XBO version of Halo 6.
