It's wont look like a failed promise. The box is (apparently) capable of hitting massive 4k on most popular 3rd party engines.
If devs decide against shipping a 4K game, it won't be because the box isn't truly capable. The ARE free yup ship the games however they want and ME couldn't be more clear about that.
It's know TFs aren't the the entire story, but to hit true 4K in comparison to sony's checkard board on the pro, they need to increase resolution by 100% with only 40-50% more GPU power. The math doesn't make sense unless sacrifices are made elsewhere.
If devs chase true 4K and in doing so drop a few more frames than the do on the Pro, the headlines will read "Scorpio performs worse than PS4 pro" that's what happened to the pro when it dropped a frame or two while doubling the resolution of PS4 games.
I'd rather see devs use the power the way they want, and yes they are free to do what they want, but not completely free. Microsoft is trmpeting true 4K in their marketing which sets soft targets for devs, if only to appease what they think Microsoft wants or their consumers want.
My original post was not to cast any negative light on the Scorpio, but to point out that Microsoft is putting themselves in a bad spot with the "true 4k" marketing and I hope that they stop. Unfortunately, from what's come out from them in the last few weeks, it seems like that's don't intend to.
The Scorpio looks like it's expertly engineered, and they did a great job being aggressive with the tech, MS shouldn't let it down with poorly thought out marketing or marketing that is based of of what competitors are doing.
