st1llwell: Just curious as I much prefer physical media, especialy for the art books and things like that.
If you mean in US...you'd need to ask Warner Bros, I reckon. Chances are they are the ones that said "We don't want physical, it's all about digital here.".
If you mean in other places, like Europe...physical is very much available.
The description for the game (both Collectors and Standard editions) in Polish clearly say that included in the game are discs with the game ("discs" as in plural, meaning that it's unlikely it's just with a text file with a code, too). The digital download seems to be in addition to the discs themselves.
EDIT: It seems that the store page shows something else than the teaser page, which is weird. The official teaser page shows discs with the game only for standard edition, but not for collectors. The shop describes as said above. One of them needs to be wrong...
