I don't think anybody knows about the hardware yet. The photo of the prototype is an Atmel ATMega: not an ARM core, no BLE radio; extremely unlikely to be involved in the final design. I'd expect they'll use one of the Cortex-M0 uCs with built-in BLE radio (like those made by Nordic or Cypress). Microcontrollers tend to be nicely open from a software perspective.

>I'd expect they'll use one of the Cortex-M0 uCs with built-in BLE radio (like those made by Nordic or Cypress). Actually, it sounds more like there will be a Freescale Microcontroller on board: >Both Freescale and Nordic Semiconductor are working with us on making this initial 1 million devices a reality. Freescale do make Cortex-M* uCs (the Kinetis range), but do not make any with BLE, so I suspect that the main micro will be Freescale, while Nordic provide the BLE radio. Most MBED dev kits use two microcontrollers, one to provide the USB interface (ARMs CMSIS-DAP Protocol), and one that actually runs the code, so the same is probably the case here with the Nordic SOC providing both BLE radio and USB interface.
