On the reddit thread where a guy has watched loads of the different previews he's found one outlet saying the soundtrack is purely a remixed version of the originals soundtrack, so it won't be dlc.
I hope your right.
The Hunters could lop your head of in the original games.
If they can't in this it will be super lame.
Also regarding the gore a lot of people speculating for the b roll they were playing the Japanese censored version, which is re2 removed a lot of that.
