An anonymous tipster, who shall remain anonymous [Thanks, Frank!] tipped us with this little gem:
Before the DS came out, Nintendo was actually working on a WiFi adaptor for the Gameboy Advance (which they ended up integrating into the DS, which was originally just going to be a bit of an upgrade to the GBA). So the idea of having WiFi-enabling connectors on the Micro seems pretty likely.
More as we get it.
