I'm with scottfa
It will tick me off if the bug fixes(if any) can only be downloaded for a fee.
If there are fixes to things that were MARKETED (this is for Carl) to be in SONAR 8, then you can't morally charge for finally making them work.
You can charge for something new.
I guess we'll just have to see what the 'upgate' is.
If there are new things and Cakewalk charges, they should also provide a smaller "bug fix" update to those who don't want the new features but just want their 8 to be a little more complete.
