In theory, yes. that is of course if nintendo doesn't do something about this soon. because wiiware game makers are not going to want to release their games on to a compromised system.

 

I"m with asher,
I think that even though the was installer thing is a big thing here, it only effects a small part of nintendo's consumer base.
If it was that big of a problem, nintendo would have fixed it by now.
Like the trucha signer, they only put the IOS37 in there to scare Datel, but they have not even activated it yet.
