I am truly hyped for this new Zelda. Coming off of TES 4: Oblivion, I'm going to love the new open world the game has to offer. It also addresses the issues I've had with previous Zelda titles, such as the somewhat vast, yet empty world of Twilight Princess, the constant reminders of Skyward Sword plus a really cool glider, and it even improves upon Wind Waker's weapon system!
I'm also intrigued by the climbing system and how similar they have the (impressive) music set up comparing to Shadow of the Colossus. I'm really curious if they'll include any bosses in the style of SotC, as Nintendo was actually planning a similar huge climbable final boss in Ocarina of Time.
