While I will play my Wii U for many more years... I'm about done
I bought my Wii U nearly three years ago to the day. For the most part it has been a great experience. Very satisfied with the purchase. Barring some pleasant surprises at E3 or in the fall, I don't see myself getting much more.
Always up for Mario Kart and Smash. Still have a ton of games to finish. In fact, if the NX did launch this year, I doubt I'd get it at release b/c I have too many games to play as is.
