Internet connection needed to get pre-order DLC?

[Just Because]

Hey all i know its probably been discussed before, and MCM has posted details about the free DLC, but i was just wonderin whether you need xbox live or PSN to claim the free stuff.

I guess there probably isn't a certain answer but does anyone know from experience of similar games whether you can just get the stuff without internet connection?

Might sound like bull to you but i dont know whether its possible..
