I really do want that documentary, and the steelcase looks nice. But i hate that there's middleground between the collector's edition and Day one. Why not just scale back the collector's edition a bit to include the fancy packaging and documentary + some DLC and call it a limited edition, because for as much as i love MGS i don't want to pay extra for figurines that will only take up space and collect dust.
I like how Fromsoft is doing it with Bloodborne. You get the art book, soundtrack and a nice case to fit it all in. And they have the bigger version too with some extras for anyone who wants that.
But yeah, the first of September. Can't wait!
