I doubt they would offer it as an "exclusive" reward for buying a deluxe edition and then immediately make it available to everyone else.
That said, very little that they've done as regards the marketing of purchase options makes much sense. I've never seen such an expensive collector's edition. Nor a game with mutually exclusive premium editions that required you to buy more than one product to get all the possible features.

And they wonder why customers feel fooled...
That'd be nice for a change instead of Germans important that stuff from UK sites to get an English version.
