And I do get these threads - we all have different needs, love this hardware, want it to be better and not share the fate of Virus. As much as KPA sounds and feels great its hardware is outdated and due for revision (I'm talking about Toaster). Audio via USB is a standard and useful feature nowadays. Startup time of over a minute sucks big time (during my latest gig we managed to blow up fuse and power down the whole stage) - when we got power back all devices, except my KPA, were ready to go within 10 - 15 seconds, KPA needed over a minute. UI is noticeably slow on Toaster when you compare it with... pretty much any gear produced in last 5-7 years.
KPA Stage is a step forward in a sense that its main CPU is much faster, but still misses modern means of sending audio to / from computer. Not to mention that lack of MIDI via USB (every single device which as USB port I came across do it - KPA chooses to stay behind, for reason I just don't get).
I care less about touch-screen, although it would be a good addition. I have a few synths, some with touch screen, some without - the one with touch screen is way more convenient to use. But synths have very deep structure to tweak - KPA is super simple, so touch screen wouldn't probably help much.
