It depends. A project _of defined scope_ that has no schedule pressure can go pretty fast. If the PMs concentrate on squashing change (or moving it to version N) instead of bugging people to get something out by a date, that can work. This is especially true if there is some cool problem in the next version that the developers want to get to but can't until the current version ships :)
