Not exactly sure why "high end" would equal "rack". IMO that's quite an antiquated thing.
Sure, studios have racks, but even in case you use the thing for recording only, you might still want to control things on the floor, add pedals to your board and what not. Sure, doable with a rack as well, but most people I know prefer the floor versions.
Anyhow, I'm sure there's gonna be a rack version, but as the various floor versions have been vastly more popular (and that's likely by any margins between 10x-100x, maybe
@Digital Igloo could share a little bit of insight here), it possibly would be the best idea to release those first.
