Windows Vista has shipped, been released to manufacturing, the horse has bolted, the gene is out of the bottle, the submarine has sufaced, etc etc. If you have a windows application, you should have already completed your testing and have any required patches available, now. Not next week, not next year, now. Even though the general retail release may be a few months away, the techical early adopters, i.e. the ones that decide where IT budgets get spent, are already using it.
So test, test, test, test, test and test some more, then ship those patches. Because people like me are looking for them now.
