61 keys, with function, arrow, and editing keys hidden under an Fn layer, ala Happy Hacking Keyboard, but differently. The keyboard controller that he's using can be reprogrammed quite easily, so you can remap the thing however you want, and even create some macros, as I understand. Ideally, the production version would have an IBM TrackPoint III or IV style pointing stick, but it will most likely have an Alps StickPointer (what Dells and HPs with pointing sticks have.)
Keyswitches would most likely either be Cherry MX or Alps-style. (And possibly both versions would be produced, with your choice of switches - black (linear,) brown (tactile but quiet,) or blue (tactile with noise) Cherry MX, or white (tactile with LOTS of noise) or black (tactile but quiet) Alps.)
