I'm going to get a grey one because I don't think I can handle multiple colours beside my TV. It would drive me nuts.
I'm going to sit out the launch, though. I was prepared to get one on launch, but it needed to have Zelda AND something else for me to buy right away. I already have a WiiU, with Splatoon and MarioKart 8, so those announcements were cool, but I probably won't double dip on both just yet and since Zelda is available for the WiiU I can just wait a bit.
I'll probably buy it once Mario Odyssey comes out, and hopefully by then it'll be $400 CAD with a game or maybe an extra controller or something included. Right now it has exactly one game I want that I can already get on a system I own, so I wait.
