Colevrak sets aren't selling that much anymore on all KAT offerings. The first few sure did, because "Finally! Colevrak!". After some time this has saturated a bit. And I take into the acount that when a non-Latin monolegend kit is offered, Colevrak users can buy that instead and are paying less than alphas + Colevrak kit.
Since this set has a different look than other KAT sets and there are no non-Latin legends on offer, I honestly believe Colevrak kits will do fairly well. KAT Space Cadet offered something truly amazing for alternative layout users: Stand alone Colemak and Dvorak alpha kits. It also had a mono cadet legend kit, so Colevrak users were spread out over three different kits. They didn't sell huge, but still okay, I'd say.
