To piggyback what others have said. A lot of people, even those that can afford an expensive PC, simply don't want to game on a PC. I'm one of those people. I can very easily buy 3 to 4 high end pc gaming rigs right now, and still have plenty of money to spare, and I choose not to.
I'm someone who will upgrade my PC at some point, just something I like to do, and I do sometimes game on the PC. It use to be my primary gaming platform for years before the xbox 360 came out, but that is no longer the case. I still occasionally use it to game, though. I played my 2014 game of the year, South Park the Stick of Truth on PC, and I did the same for Tomb Raider 2013, but I have no immediate, or even future plans, for doing the majority of my gaming on anything other than a console. That includes Scorpio, and that includes, more than likely, a Neo unless there's a surprise announcement and Persona 5 ends up coming to Xbox. Gotta be honest, though, with God of War and Horizon Zero dawn looking like they do, and that damn Spiderman game, there's just way too much of a pull for me to ignore the new PS4.
