This just in to me via phone from BMW.

The X3 2.5 will continue on unchanged in 2006, in Canada, with the exception of revised panels and bumper painted to match the body. The engine will be the same 184 hp unit as 2005.

That's pretty much the news I was expecting to hear. They weren't about to drop their biggest seller, despite what is happening in the U.S. Smart (lucky) decision in light of the recent increases in fuel prices.
