Greg Shields: RC0 was released on 9/24. RC1 was released on 12/5. That’s not quite 10 weeks between releases. We’re 12 weeks away from the launch date. For Vista we had an RC2 that was released 4 weeks before RTM. But that was a bug fix release only, as I remember…yes?

So, my gut feeling is that we’ve got to be supremely close to “feature complete” with this one. As I’ve heard there are a number of big changes in RC1: GP Preferences, WSV, WGA, others. But there is likely to be some changes relevant to the Vista SP1 release, since they're sharing codebase. At the same time, MS is laser-focused on meeting the Launch date, to the point where in my opnion they'll drop features to make it rather than slip.

Thus, I suspect we may indeed have an RC2. But that RC2 will be dropped mere weeks before RTM, and likely won't include any functional changes. Only bug fixes and code optimizations.
