I have been following the development of CB v2 and would like to know if their are any plans to release a full v2 CB before my expensive developers licence expires. My project requires some of the new features that v1.9.1 doesn't offer.
As your membership doesn't expire this year, I can answer with a YES for sure.
Regarding exact date, it will be released when ready and stable. But I can only give you my current guess: RC got released 8 days ago. RC.2 (with all reported bugs fixed) should be released in the next days. Then we might have another very stable RC shortly before the (completely) stable release. So it is a question of weeks only. From there on we should have new releases quite often (very backwards compatible as usual).
