Given the scorched Earth approach they have taken with their criticsm of the Avid BB7, I'd really surprised if that happened.

The only way I could imagine it would even be plausible would be if Avid made some type of change to their brake that the Big-S could spin as some type of 'safety enhancement' and I just don't see that happening because there just haven't been any problems with the Avid 'as is'.
