Hard to tell this early.
At E3, Phil seemed to stress "premium price", and all of MS has backed that up since. It also makes sense in the fact that MS may be trying to cater to the high and low end of the console market, because PS clearly has the mid-tier level all locked up.
It depends a lot on what "premium" means exactly to MS. PS said numerous times that Pro would be a premium product at a premium price point. PS clearly thinks $399 means premium. Its possible based on that, Scorpio could perhaps be $399 as well, but that would almost guarantee the cpu is jaguar again like in the Pro.
I am willing to bet MS charges minimum $499 just like the original XOne price. Even with all the backlash and hatred thrown at MS, the XOne still sold very well. Not PS4 well, but much better than the 360 did when it launched. If MS can try the same approach this time, minus the DRM and Kinect, and add much higher spec'd components as compared to the Pro (excavator or zen cpu) the Scorpio should sell much much better than XOne did.
If MS sells Scorpio any higher than $499, they will immediately lose a lot of early adopters, unless they throw in a bunch of AAA titles or free Live service for a year or two in a bundle. I don't see that happening. Odds are good that Scorpio will be $499 (even if MS has to eat $50 to $100) and Pro will remain at $399 but will come in a bundle with a game or two, just like how PS4 did a year after launch.
