Again, "modern Zelda" is too loosely defined. The only way to break from it is to change it so much that there's no point in calling it "The Legend of Zelda." It would need to be the biggest reboot in gaming history. They'd have to ditch dungeons, change the setting (both place and time period), have no more puzzles, make a totally new weapon system, add full voice acting, make a new combat system... Really, make a new IP that's Zelda only in name. The franchise has hit its limit. I hope they just focus on making the Wii U game the best one so the series can at least go out with a bang. In fact, I want them to make it a launch title for the system after Wii U.
