It looks cool, but it appears to take a lot of special keys, doesn't it?
You haven't seen the options.
It supports 2.75u or 1.75u right Shift, 1.25u or 1.5u bottom-row modifiers, 7u, 6.25u or 6u Space bar, 1×1u or 1×2u numpad-+, 1u or 2u numpad-0, 1u or 2u Backspace, ISO or ANSI Return, if 1.5 mods you can choose between 1 or 2 1u keys between right Alt and Ctrl, you can have two 1u keys instead of a 1×2 numpad-Enter.
Click on the first "More" link in the first post to see some of the options for the bottom row. There is also more to see if you study pictures of the PCB carefully (links in the first post). Support for ISO Return key isn't there in the shots of the PCB, but we have been promised it for the revision that is going to be offered in this round.
This keyboard is like the GH60 + GHpad in one case, with all the layout options that it has ... plus the option of arrow-keys in the space in-between plus
backlighting. And if all you wanted was a 60% keyboard with backlighting, you could order the PCB, easily cut away the numpad-portion and put that into a Poker-compatible case.
The controller is an ATmega32u4 - the same as in the Teensy and the GH60, plus a chip that helps with backlighting. I expect to be able to convert any of the open firmwares that exist out there to work with this board (without backlighting at least).
Edit: I discovered even more options that I hadn't listed above.
