I think so, too. I think anyone who has really wanted one shouldn't have had much trouble getting one in Canada even in the past few months... really just need a little persistence in searching. I'm not sure it's the same yet in the States.
This thread is the perfect example of the Canadian situation, I think. In the hour since I posted the link, they're down a whole two units.
Still, it's scary to think that it's taken this long to get to a point where it's not an insta-sellout... and that Nintendo should have enough latitude on pricing that they can probably still keep sales going at a similar clip with a price drop.
