To me, this new software version taking 6 months already with no release is exactly the pattern of multiple previous Kemper developments - the delays, the reverbs, liquid profiles, the trems etc etc. Many of those took 9 months or more from when they were first shown at an audio show like NAMM or the Messe to being downloadable as a free OS revision. Sometimes, the beta release phase went on for some months beyond the first release.
I imagine that, to CK, this is all business as usual and all the chatter online is of no consequence - the dogs may bark but the caravan moves on as Paul Keating (Australian politician) used to say.
