Considering this game is still being designed for Wii U, "some weird controller gimmick" basically amounts to "It's Zelda with a map on a second screen and gyro-aiming." It's nice to see you again, 2011.
Nintendo made the proper adjustments to the Zelda formula in A Link Between Worlds. It sits the middle of the original Zelda's zero hints on what to do and where to go and modern Zelda's excessive and at times, oppressive handholding. You get the sword within 10 minutes then the game loosens the reigns. With a new open world, that's a pretty good place to start. Gives players the sword and horse within 10 minutes and if they feel like cutting grass for the next 20, let them.
I'm more worried about Nintendo's weird attachment to filler content. My hope is that Nintendo doesn't pad the world with things just to have something there. If the game is only 20 hours long, make it the best 20 hours it can be. An open world is wasted if it's empty, but being full of chores is just as bad. "Collect 77 of these things." Is that fun; or is it just there?
