Found this via digg:

A developer in a big coastal American city apparently received a mysterious package from Nintendo. Office staff, programmers, and even the president weren’t aware what was inside. The box was opened, and viola, Wii dev kit. This could be a ploy on Nintendo’s part to get as many companies working on Wii games as possible.

Certainly a great way to get developers interested in the Wii hardware who weren’t curious enough to purchase the dev-kit outright once available. Could this be a trend? They do only cost about $2,000 each, at the moment. Though, at $20,000 a kit, I doubt Sony will be performing the same miracle with the PS3 dev-kit.
