I've gone the other way, and am now back on PC instead of consoles. Instead of the Scorpio I went for a 1080 instead, made more sense to me.
I do enjoy console gaming still, but I'm sick of games only ever being 30fps (for the most part) and I want to be able to enjoy them all at 60fps in their glory, as that's what makes more of a difference to gameplay. I can still use my Xbone Elite pad if I want, and now MS are releasing first party (and soon third party) stuff on PC at the exact same time it seems a no-brainer. I'll need to do a full CPU & mobo upgrade next year probably to keep right up to date, but that's just a want rather than a must-have.
4K doesn't interest me, certainly not at 30fps, although the 1080 is more than capable of running at that or higher if I wanted to turn some gfx settings down. Until the next lot of consoles come out that can do 2160/60 with ease, which isn't likely for a long time, I'm staying PC.
Interestingly, console FPS gamers on-line consider using M&K to be cheating, and will give you a ton of abuse for it. Personally I don't care as I don't play on-line, but I just found that interesting.
