It's not as unwanted as reading GAF would lead you to believe.
I think the one thing that's maybe a bit hard to understand is why they didn't make DK their second Wii U game just for variety sake. I imagine if Tropical Freeze came out when the system already had X, Smash, Zelda, Metroid released it wouldn't have been so disappointing to people.
For me personally I'm fine with it, Tropical Freeze is my most anticipated title.
