So D3 won't ever appear? At least in many open source projects the final released is tagged one to two weeks before the final release. Distributions have then time to repackage the release. Meanwhile, the core developers are already enthusiastically implementing wild new features after a long feature freeze.

It's similar kind of tick-tock as Intel has with their CPU line (1 smaller process -> 2 improved core -> goto 1). In successful software projects they have alpha/beta period, feature freeze, stabilization period, release, new alpha/beta period etc. Concurrently new bugfix releases come out just like with D. I haven't heard of new features lately so D2 must be stabilizing now.
