I'm under NDA, but I believe we can talk about things that have already been disclosed.

If you do a google image search for large micro:bit images, you'll see there's a Nordic NRF51822 chip (Which is an ARM Cortex M0, with BLE), and a Kinetis ARM chip connected to USB. It's running an mbed-compatible bootloader that appears as a USB mass storage device. You just copy hex files onto it and it programs the NRF51822.

Does that google image show any markings on "Kinetis ARM chip"?

Ok, Wikipedia says it's KL26Z, also 16K RAM, good. I was concerned there may be some cheating with higher RAM available on it. But nope, folks now will really need to optimize stuff to do something useful in 16K ;-).
