Toys R Us in Canada has apparently been accepting $50 deposits for preorders for some time, you may want to check there. I believe preorders are generally being discouraged for PS3 and Wii, though. Still, check around - no doubt Future Shop and Best Buy, EB Games, etc. will have something to say about preorders soon.
