Kinda' missin' the point of "exclusivity", aren't you?
Not at all. By itself, giving one retailer the exclusive rights to the CE isn't a bad thing... as long as that retailer is available everywhere. For example, if Amazon had the exclusive rights to this, then I wouldn't have a problem, as Amazon ships (almost) everywhere. But Gamestop? They're only available in a very limited amount of countries, they don't ship outside of those countries, and even inside these countries, you often can't order it off their website and you have to order it (and pick it up) at a physical store. Giving Gamestop the exclusive rights to this CE was just about the worst decision EA could have made.
There's a big difference between exclusivity and unavailability. EA should have at least excluded countries that don't have a Gamestop (and where Gamestop doesn't ship, which is usually the same) from the deal, so that they could make another exclusivity deal with a retailer in those countries (or EA could sell it themselves, in those countries).
I'm confident CD Projekt will do this a lot better, with their Witcher 3 CE... now THAT is one CE I am looking forward to with confidence, and a company that I will gladly give my money to, as I feel they deserve it. EA doesn't!
