I'm ok if it's a won't fix in diablo and you fix it in fremantle, but if it's fixed, I'd like to know how it's fixed.
I know you've got an NDA on it so you can't comment much, but then, what's the point of marking it as fixed?
I like to see Bugzilla as a collaborative tool shared by developpers and users to exchange their views on some software.
Marking bugs as RESOLVED without telling anyone what you did to resolve it doesn't seem much interesting to me. Now the bug is not in the OPEN state anymore. So noone is supposed to be working on it anymore, while it's not fixed in Diablo. And noone will bother working on it, since there is a fix, in Fremantle.
