Welcome.
It is a big ouch that Canadians still pay a premium, even though the dollar has caught up to (or at one poit, surpassed) the US dollar. Perhaps a road trip down to the States is in order.
For the price increase ... I did a little comparison of 2007 vs. 2008 prices here:

The catalog is often clue as to which styles are going to be discontinued ... if it was in last year's and isn't in this year's, AND still on the shelf at the local Ikea, expect it to be discontinued during the year.
That said, the catalog sometimes accomodates for production problems too ... Arlig beech, Arlig medium brown, and Nexus black-brown come to mind, as they exist, but production issues have held them back.
