Well, it's not a storage solution, but here it's uh ... something: Nintendo of Japan have revealed that they will be releasing a Wi-Fi network adapter in Japan on September 18.

Yup, it does appear to -- more or less -- be a Nintendo-branded, sexy looking wireless router that will match both your Wii and Nintendo DS. It doesn't look like much set up will be involved, and it's likely that Nintendo is releasing a product like this to make it as easy as humanly possible for owners to connect their Nintendo devices to the Internet. The official page notes that other devices should work with the adapter, but only the DS Lite and Wii are guaranteed compatible. 

This definitely seems like a rather silly peripheral, especially in light of the fact that a lot of gamers have been patiently waiting for a hard drive or other storage solution for the Wii. Still, this may be just the thing Nintendo needs in Japan to really jump off their online services; if there's one thing I learned from my short time Tokyo last year it's that Wi-Fi and Japan aren't good friends yet. 

No word on an North American release, but if it were to come Stateside, we're betting on an extremely limited release.
