That quote and those numbers are incredibly misleading, I'm not sure why they use that to prove Node 0.12 isn't coming soon. If you actually look at the issues on Github, only around 30 of those are marked as 0.12, with the rest being various other milestones including 0.13 and 1.0. It has also already been stated that there is only one more 0.11 release before 0.12.
No one is trying to "prove" 0.12 isn't coming soon, we've put lots of work into it, and look forward to its release, and its got some great new features.
I'm not sure the tag states are always up to date, perhaps they are, but the fact remains that 0.12 has been "real soon now" for quite a while, so saying it might be a while still is a pretty safe statement.
The core team is working hard, but I think the PR queue is a good indication of how scarce a resource review time is.
