During a panel at PAX East, Bethesda revealed to the crowd that the upcoming DLC The Dark Brotherhood would be hitting the public test server tomorrow. While this is not a full-on release, it is the step just before.
“Breaking news from the #ESOHQ at #PAXEast: Dark Brotherhood comes to the PTS on 4/25! #BloodWillFlow”
Along with that, the devs answered many fan questions, including:
“Player: How much stuff can I stuff in the upcoming Craft Bags? Rich Lambert: A shit-ton. #PAXEast”
Also promised are new mounts, equippable potions, and changes to stamina.
