How many RCs do we need for Vista?

Vista RC1 has been released and even if I read some people enjoy a new stable version (better than the July CTP apparently) some other bloggers have doubts on the 'almost ready' statement.

If Vista is RC in September, does it means Microsft is really ahead of schedule and could release anything before January?

Not so fast! Well I don't really share the view that Microsoft is abusing the RC1 appelation (again one of those conspiracies theory!), but probably we might expect more releases between now and January.
