Well... It seems to me that the only reasons Kemper would "need" to release a new hardware platform is if A. The existing unit finally ran out of memory and/or horsepower to continue the present upgrading approach, or B. Sales of the current version dropped below a specific threshold due to not being competitive in its market. But if the current model is still meeting all sales goals, then I don't see any reason to fix what ain't broken.
...or if they came up with something that was a step change.
Like i think you are suggesting, I don't think dual amps and touch screens are enough to warrant an upgrade but Kemper might introduce a step change again ( that's my hope).
I just think that we have such high quality already that its the law of diminishing returns so they need to think in terms of a step change....
