Yeah the article seems to suggest that it's not allowed in Canada. I'm seeing more than a little speculation going around about this, but most of it just griping and complaining, rather any explanation for the actual reasoning behind it.
It kind of bugging me, honestly. If it was just a dumb
PR move, or some shade of general corporate greediness, I'd just roll my eyes and move on. But I'm just not seeing any clear-cut benefit to this, beyond the possibility that they're trying to use a jacked MSRP to imply a given card is better than it really is. There's been rumours of impending price cuts to GTX260 and 280, (even before actual release) on account of stronger than expected competition from ATI, so perhaps this is them trying to gracefully maintain that the cards are worth a lot more money than retailers will wind up selling them for?
Eh, I dunno. Maybe Monday will bring some plausible news on this.
