The Register has an article on the new Raspberry Pi3 which is currently going through FCC testing and certification.

The Pi 3 Model B otherwise looks pretty much like 2015’s quad-core 32-bit ARM Cortex-A7-based Raspberry Pi 2: it sports a familiar Broadcom system-on-chip, HDMI port, SD card slot, wired Ethernet socket, and 40 general-purpose IO pins, all in a credit-card form factor. – Source The Register

Not much is know from the rest of the submission about its features, however Wifi and Bluetooth onboard it will be interesting to see what other things have been built in as the details of this version are released by RaspberryPi.
