It is really a philosophical question.
By demonstrating that something is in the works, you generate hype for your product. You also cut off some people from purchasing a competitors product knowing that a really big new feature is coming soon.
There are downsides. You tip your hat to the competition, and your users get agitated waiting on the new feature(s).
It has been my experience with my KPA since 2013 that CK provides quality updates. The new delay’s were done incredibly well. Morphing was outstanding. I fully expect the new verbs to deliver.
I agree with others though. As-is, the KPA sounds fantastic today.
