Much like many of us have posited in the past, Microsoft are introducing the successor to the Xbox One under the pretense of Scorpio being a "generation-less" device. The Xbox Two or whatever they end up calling Scorpio is an attempt from Microsoft to try and get the jump on the PS5, and if you've been following this business from the 90's or even before that, you would know how effective a first-mover strategy is in the business.
Do I think the strategy will work? Long-term outlook points to no. Globally, 4K technology and 4K content is still in it's infancy, and while 1080P is on it's way out, it's a much slower transition than the move from SD to HD. 1080P is the standard for all screens, so 4K -- be it native on PC or checkerboard on the Pro/Scorpio -- is going to need much more penetration before it becomes a big selling point for a product. By the time 4K technology and 4K content hit the sweet spot of being cheap and plenty enough -- 2 to 3 years from now is my guesstimation -- the PS5 will be launching. Globally, that's a nightmare scenario for Scorpio, because it will be sandwiched between the cheap 4K device (PS4 Pro) and the less cheaper 4K device (PS5). That's what happened to the Wii U, i.e. it was sandwiched between cheap 720P/1080P devices (360+PS3) and less cheaper 720P/1080P devices (One+PS4).
Based on the rumors from Digital Foundry, the hardware in Scorpio sounds much more conservative than what people expected. I could be wrong, but this says to me that Microsoft are targeting a launch price ($399.99) that's in alignment with the launch price of the PS4 Pro. I wish more developers could divulge the specs of the console, because that would paint a clearer picture of what fall 2017 looks like for the business. Regardless of what the final hardware has inside, I think launching a new console at $399.99 is good, and this will afford Microsoft the opportunity to target people who want Xbox games to be running in 1080P across the board.
