I think I got the first part of your post.
Currently Homebrew works off SD card, no alternatives yet.
Tear up the Wii?
No idea what that means, I'm sure the Wii doesn't get too upset by the use of SD cards and it's a non envasive procedure plugging the SD in.
Also No Twillight Princess game.Neither Twillight hack.
I think I will leave the third part to someone who thinks this makes sense.
