I agree one format will probably work best. My only concern with going with 60% is it may cannibalize some KBP V60MTS/Matias 60% sales
I share your reticence for cannibalizing on Matias' upcoming 60% GB especially since he started it at the behest of this community. That said, we might be able to skip any ethical dilemma for this round as the responses so far are leaning in favor of TKL.
There's no ethical quandary with someone else doing a 60%. It's business and business means competition. In any case, I know I have no interest in the Matthias 60% due to the layout and caps. I also wouldn't say it was at the behest of the community when he saw an opportunity to capitalize on.
Also, Matthias will make money off switches people buy for it and potentially caps as well.
Lastly on this matter, since it's a Gon, this is a Korean custom, something that doesn't typically compete with cheaper options like the Matthias and V60MTS. If anything, it's competing with Duck and his keyboards.
Don't take this as me being ungrateful or bashing Matthias, just providing a counterpoint to what's being said.
Lastly, I know I'm just one voice, but I've been pushing for a custom Alps 60% PCB well before anyone started making one and before there were talks of one. I even tried to see if I could mod the GH60 files to be Alps compatible (and failed). I love Alps, but I wouldn't order anything if it was TKL, but plan on several as 60%.
In other words, why not both?
