Hello,
is there a blog or forum site where we could see very rough overview what to expect from new versions of krakatoa (like 3.0, and if it is planned at all 
. As well as other great thinkbox plugins?
Of course if there are people who have time for writing that.
Otoy guys (from octane render) have this habit of monthly update of what are they doing now and what is to be done next.
There is no such place currently.
We sometimes share development stories and WIP stuff on our Thinkblog, but there are no current items for Krakatoa right now, mostly for Deadline 8.
We just shipped Sequoia v1.0 which required a lot of development resources. We plan to update several of our existing products next, but we cannot offer any details yet.
