Sorry to join late on this thread. @2wet: I believe the WiFi issue has been solved after the OSBo pre-configured image has been updated back in August. OSBo will continue to be offered and there is no plan to discontinue it at all.
@denis.french: all P8 and P9 pins are mapped out on OSBo. You can check the user manual page 9 for details:
The WiFi adapter is placed on the side with P8 pinout, covering about 10 pins. So that region will not fit standard pin headers, but the adapter is well above the PCB, you can definitely solder wires from the PCB to connect external components.
