I'm sure that even if or when there will be a new kemper sometime several years from now with some new features it will still be back compatible and can play the exact same sounds from the profiles we users have created today. They designed their Access Virus series with longevity in mind. The first generation of the virus sythesizer is from 1997. Even the old models still get firmware updates and can be serviced. I don't know another product in this category that is so future proof. That is a big difference compared to Line6, Axe fx, Boss gear etc that drop the support for older products when a new model is released. Fractal releases new Axe fx products every 2-3 years dropping support for older gear. I also really like that the Kemper sound doesn't change after firmware updates like the Axe fx 2 that I have to spend time re-tweaking, not having a consistent tone each fw.
Here is info from a thread about the kempers long planned lifespan.
"Why the Kemper is really future proof for at least the next 15 years"
Quote from C.Kemper.
"We have no plans or ideas to improve the core sound engine of the profiler in terms of getting closer to something.
If we ever applied changes to that in the future, we will still make existing profiles and rigs sound the same.
My plan is to let your profiles and rigs sound the same in 15 years, as
you have created it today. No matter what hardware, software or firmware
you run it on. Of course there will be improvements and paradigm
shifts. But no technical innovation can algorithmically improve the
sounds that you have created by 20% or whatsoever. If there is an
innovation, you will have to add it to your sound by hand and in
purpose."
