"We had the ability to look at doing an interim console this year if we wanted to. We thought about that. But we didn't think we could deliver, with the silicon that's out there, a true 4K gaming six teraflop machine this year. So we decided to wait until we hit the real spec that people were asking for."-Phil Spencer
That right there tells me Scorpio uses no Polaris GPU. The Silicon that has yet to enter the market is Vega- which has a higher perf per watt/FinFET scalability.
Vega is AMD's architecture aimed to battle the 1070/1080...so that is the perf level to expect....especially taking DX12 into consideration.
That extra year means no settling for checkerbox upscale on nearly every title and more native 4K games. When you look at Gears Ultimate Edition/Gears 4 /Forza Apex profile around 4K you end up with a 980Ti GPU...and that's no coincidence. They are going to massage that perf level in their games.
