I have my xbox softmodded... I don't need to have a mod-chip to play "backup" games. I just burn and play.
The only way there will not be a softmod for the Wii is if the disc's have built in security... like the old PS1 games with the intentional bad data written to it. But even that can be forged with a properly hacked OS.
Just wait a while longer. When the Wii OS is finally dumped, someone will find a way to upload it again. Then someone will find a way to "fake" the signature of real Wii discs, and poof, softmod!
