Late to the party, but getting on one of the big new consoles should be a plus for anyone. Sure, Sony has the most popular console by a wide margin right now but that could change if the Scorpio machine blows the PS4 Pro out the water.
Wii U was a nice gesture, but you were kind of left to the wolves at that point plus the system is all but dead for some time so I wouldn't expect any benefit out of it anymore.
If I knew they were going to make the Xbox One into a dev kit, I never would of sold mine. I kind of wonder if you can do the same with the Slim model?
My only other concern is that while it's great that MS wants to let more indies create games, do Xbox players actually want them? Maybe I'm speaking past tense but many Xbox One owners locally and some online seem to stray away from indie games. PC is a totally different ecosystem.
