The release of a kpa2 would mean the end of software development.
Well, maybe, yeah - but I mean, it is ok to step up the hardware after some point.
People are always asking for improvements, but there's limits to what and how fast can be computed. When you reach the ceiling, either you upgrade the hardware, or start cutting corners.
Kemper has already proved - I would say, after 10 years! - that they're not that kind of company to release a new hardware every 2 years just to get money out of our pockets, so I am sure if they did it would be to actually to bring next-level algorithms to the table, and given the quality shown so far I would buy something like that in a heartbeat.
