my Xbone continues to collect more dust than an abandoned library book. I'm seriously considering trading it in towards a Wii U.
I won't tell you to sell your XBone as I really don't know if it's a good or bad platform but I own a Wii U and I spent a good trade of great gameplay hours on this console.
Super Mario 3D World, Yoshi's Wooly World, Mario Kart 8 and Smash 4 are wonderfully crafted games that offer great polished gameplay. Bayonetta 2 is as well a hit, I personnally don't like the artistic direction of the series so I skipped it but I know Platinum Games always deliver on their main franchises.
Playing those games with a Pro Controller was really worth buying the console, for sure.
And back on topic, yes I preordered a PS4 pro because, you know, playing Bloodborne with better framerate is my wet dream.
