Neither would Nintendo. The rumors of a price drop turned out to be bunk, or even bunkum if you prefer. George Harrison told Reuters that "We'll stay at $249 for the foreseeable future. We are still selling everything we can make."
The situation may be slightly different up in Canada, where the Wii seems to be dropping in price to $269 because of the rising Canadian dollar. We have yet to see confirmation on that, so into the rumor bin it goes.
