Amazon.ca leaked information on pricing of Adobe CS3. If you go here you can see for yourself. Photoshop CS3 will cost 895 CAD, or the equivalent of $770 USD.
Just a little refresher, CS3 will run natively on intel proessors, so it will be much faster for those of you lucky enough to have one. Also it is said to have significantly better features and usability than the current CS2.
