Unless the way to unlock the DLC requires a new character or possibly is unable to unlock at end-game because certain events/bosses killed had already occurred. I am just parking everything for now. Who knows how it unlocks, I just hope it's not as convoluted as AotA.
For those on PC who don't know, you can make a copy of your save file and then use it later, if you'd like to have a character who's prepared and at the end game for when the DLC comes out. Then, you could have that back up and continue playing into NG+ until we learn what the DLC requirements are.
Here's the folder location
Code:
C:\Users\*Username*\AppData\Roaming\DarkSoulsII\*a bunch of numbers*\DARKSII0000.sl2
Or some filename similar to that.
