TBH in this particular case the project manager would be the first to admit that the current release (which was a substantial rewrite of an already functionality-super-rich product) was way too big a piece of work to do in one go. But there was really nothing that could have reduced the time between the releases much below 6 months or so. I certainly wouldn't call it a "waterfall environment" though! To be fair we are doing regular nightly builds that are accessible to the public, but they're very much pre-alpha and buyer-beware type builds that don't pretend to be suitable for most users.
