Oh god, no. Why would MS focus on Scorpio over the S? Because it has more power? The Pro has more power and it isn't selling. The market doesn't care about power, the market cares about games, and right now, they are cost sensitive.
The Pro is ultimately going to fizzle out, just like the Scorpio will, because the only thing either machine are offering is more 'power' for the same games you can play. The Scorpio won't have anything the Pro doesn't - its not a new generation, it won't have exclusive software, and its going to literally be a beefed up X1.
What we keep seeing, particularly in NA around the holiday, is that lowest-cost bundles with a tentpole 3rd party offering moves the most units. The reason why we won't see MS putting forth the Scorpio first in this way you think they will because the biggest differentiator the Scorpio will offer is native 4K rendering, and thats not something you can showcase on games in commercials. Outside of native 4K, they are going to look pretty much equal to what the X1 is running, save for some technical enhancements (framerate, AA). Its going to be the same situation the Pro is in now.
The only thing the Scorpio has going for it is power. And we are seeing that the approach 3rd party is going to take with these mid-gen upgrades is going to just have their games run with higher IQ and a few more post-processing FX. You need custom built software to showcase power, and neither console will be getting that. The console market right now has a consumer base that wants to get in for the lowest cost possible, and both of these machines are featuring large price tags for a generation that is already well underway.
Unless MS is planning on producing exclusive software for the Scorpio, and realistically speaking that is impossible as of right now (looking at their 1st party portfolio), then the only approach MS has to sell the Scorpio is selling it off the back of Native 4K rendering on games. How much mileage that will make with the larger market will need to be seen, but I don't think the larger console market is ready to give a shit about it just yet.
