Actually, if you have the WiiU GameCube adapter, DK Bongos will work fine.
I'm pretty certain it can be played with a Gamecube controller though. It's a subpar way to experience it, but it's there.
This, on the other hand? I wouldn't bet on it. That's a licensing nightmare for a game they wouldn't be selling.
Right, I almost forgot to mention this one, but... easily the most insidious announcement of the Direct. It's like they learned nothing from Nintendo Land.
Look, it's cool that they have a tech demo. It's not cool that they charge for it. I don't care if it's cheap, it is unacceptable to charge for what is essentially a sophisticated instruction manual. This is meant to showcase the product and teach users about its features, it should NOT be locked behind a paywall.
It's a bad sign of where current Nintendo priorities lie. The cherry on top of the cake that is the current pricing scandal.
