Might get a scorpio myself rather than PS4 Pro.
I have a PS4 Slim, which I adore, and I'm suddenly interested in the Scorpio, only because of how Elite might look on it vs. the PS4. For me price is a huge reason for going console over gaming PC (convenience is the other reason). If the Scorpio is comparable to the PS4 Pro in cost, I might be very tempted, especially since that gives me an entirely different platform to go along with my less-than-pro PS4. Looking at the specs, people are thinking Scorpio may be much more expensive despite what Microsoft has claimed in the past. Time will tell.
All that said, the graphics and / or framerate will need to be vastly superior to the PS4 for me to even consider the Scorpio (I've been in the Playstation camp from the beginning), and I'm going to play ED on the PS4 long enough to make sure I actually love the game enough to warrant the expense of another console. No matter how much I love Elite, I doubt I'll ever get another gaming PC. Been there, done that; never again, unless I win the lottery.
