Yes, there are more methods of installing the Homebrew Channel than with the Twilight Princess exploit. Super Smash Bros. Brawl can also be used, where you put the Homebrew Channel on the SD card and load the Stage Builder (with all custom stages deleted) in order to install it.
Zelda is not available in the current demo.
No one is selling the demo.

Actually, I think a demo has already been leaked onto a few sites. I've tried to find it but... couldn't. :D
It is unknown, but that demo for the Wii U is simply a demo. No further. Yes that game review on the Wii U is just a built in game where all u do is defeat Gohma. Most likely a Zelda game will come out later in the year for 3DS
Yes. You can use the Half Byte Loader. It takes advantage of an save game exploit found in the Patapon demo.
no only a 20 minute demo
If you go into the shop channel and click Search Genres click on Demo's and it will be later on in the list since all the demo's are in alphabetical order.
