I was under the impression that these Incubator builds are not considered beta, and that when we experiment with them, it must be with the understanding that we won't know any time frames or even IF the included features will eventually make it into a shipping product. Personally, I really like that Adobe is now giving us earlier, pre-beta previews of what they're working on, and I'd hate to see pressure put on them by developers that would make them rethink this new strategy.
Molehill will doubtlessly need to go through a good amount of public beta testing before release, and right now we haven't even reached that beta - so I'm guessing we're more than 1 or 2 months from release. I'm half expecting there to be a somewhat different set of features in the beta than what we currently have in the Incubator build.
