That direction isn't exactly confidence inspiring either, it strikes me in a similar way to Super Mario Galaxy 2: a "here, have this hardcore gamers, we'll keep endlessly retreating and not really improving on Super Mario 64, Mario Kart 64 and N64 Zeldas. Oh and a new Smash Bros of course."
Seems like more of a lip service to their few hardcore fans then anything. Nintendo is committed to the casual audience now, and everyone knows it. I enjoyed their games most back when they were developing their games for my demographic, not the Wii Sports and Wii Fit types.
The art style isn't the problem. Hell, I'd love to see an extremely bright and vibrant color palette on a console Zelda. It's the attitude behind it, that they don't really care, that seems to produce games like Twilight Princess. Technically good, but there's no soul there. It's just another Zelda adventures, with bosses, and doesn't do anything new or really interesting like Ocarina or Majora's Mask did.
