Looks like Pentax Canada is either finally noticing an issue and unfair pricing, perhaps loosing strong customer sales to other manufactures now that others have appeared to lower prices also just before Christmas. You can get a K100D body for the same price in Canada as the US for the most part:
US Pricing:

Canadian Pricing:

Makes me wish I never bought my K100D until now, to save myself $250, but I guess that's the digital camera world works, that and perhaps the anticipated Pentax press-release in Jan.
