A user had mentioned to another in the comments of one of the Lion questions that most, if not all, questions about Lion will be re-opened once it is released. This was news to me, although I would like to see where that decision was made.
I don't see re-opening all of the closed Lion questions as being an easy thing to do for all of the obvious reasons: the question may no longer be applicable since things will most likely have changed between the beta and release, and, honestly, who is really going to sit there and comb through all of those questions. I suppose we could ask one of the SE gods to do something in the back-end, but I don't feel that is appropriate for the first reason that things will have changed.
So, what do we do? Cut our losses and just move forward with what we have, or go back and reopen the Lion questions en masse? People are going ask since we have been trumpeting their being off-topic until Lion is released, so I feel as though we ought to settle this now. The same issue is going to apply all pre-release or beta software like iOS 5.
