Now that I'm thinking about it, the only consoles I've bought on launch day were the PSP, Vita, and Xbox One. And I've enjoyed the heck out of all 3 so far (although I guess I'm about done with the PSP by now). But honestly, I was more "cautiously optimistic" picking up each one, rather than "excited." It's risky to buy on launch day. You're paying the most and starting from zero. It may not go so well. I do agree with the folks that say Nintendo is a somewhat safe bet, but the 2017 market is so volatile that I just don't know.
I will also be playing Zelda on day one, because I pre-ordered it...on Wii U.
I just don't understand these folks, especially gweemz who also could have grabbed it on Wii U. After all, apart from the fact that it won't be portable, the experience will be virtually the same.
