It should be noted that Golden Keys and items in your Shared Stash will NOT be transferred. So be sure to remove the items from your Stash and put them in a character's inventory or bank, then spend your Golden Keys.
I bought Borderlands 2 and a ALL of its DLC for the 360, bought the PS3 GOTY version, and also bought the Borderlands 2 Vita bundle. I will also be buying both the Xbox One and the PS4 versions of the Handsome Collection coming later this month.
@liquidprince: Like I said, my girlfriend has only seen part of one episode of the original DBZ and still loves the hell out of the Abridged series. I think they throw enough references in there that you didn't have to have seen the original to be entertained by it.
