Welcome to the Wii cult aspher!
It is amazing to see the Wii sold out in so many places.
I'm still slashing my way through Zelda atm. You are in for a treat, while Wii Sports will show you what the controller can do, Zelda will show you the beauty of it in general gameplay.
You should get Wii Play as well, with the extra controller, I love Wii Play more than Wii Sports.
