Just an idea... If you're thinking N9, why not add the few extra keys to the >Terminal_ ergodox set and have them run that GB ASAP? They are already billing it as a multi-fit kit so it doesn't necessarily need to run with the main kit.
edit: I know it will be more expensive with the increased keys, but it may also hit a higher MOQ and thus a lower price.
I like this idea so much I'm even going to reply to myself... Hopefully I don't answer myself replying to myself cause that would just be crazy...
I'm super stoked about this idea because I haven't really been able to get a GMK set due to lack of support for non-standard layouts (I know, GMK Carbon eventually had ergodox and planck support, but IIRC, that was after the main GB ran so I was SOOL)
Anyway, I propose (again?) the GMK N9 ERGOBLANCK. Basically >Terminal_'s Ergodox kit with the accent keys removed and the planck keys added.
Future kits that work with N9 could just add blank accents for compatibility. The accent kit could look something like: 1u [r2,r3,r4], 1.25u[r3]. 1.5u [r3], 2u [r2,r4]. That would be planck, quark, bantam44, minivan, and ergodox coverage. Quark and bantam44 would have to trade for the second 1.5r3 unless two were included, but at least it would be possible.
This would be awesome... Then if we could get Colevrak support I'd be set.
