I believe it might be available on shelves though? I know that Future Shop has a quite a large selection of boxed PC games and always have any game's collector's edition. Compared to EB Games or GameStop that have very few space (Or none actually) for PC collector's editions.
For instance, two weeks ago they still had 3-4 Starcraft II Collector's edition.
I'll buy my copy on the shelves on the release date, hoping they have one. Otherwise, I'll just purchase a regular copy, no worries.
