Design decisions that have been announced:

• The primary design goals are for it to be “cinematic, exciting, conversational, expressive, cooperative, and versatile.”
• DW2 will still use 2d6 plus modifiers, rather than a different dice mechanic.
• DW2 will no longer use hit points but will use Harm instead.
• Intra-party relationships will be a focus.
• DW1 assets won’t be fully compatible without some changes.
• The game will be released under a Creative Commons license, as DW1 was!
• Luke Crane said, “Our hope is have playtestable materials for you all throughout the first part of the year and something finalish by the end of 2025.”

Cool, IIRC DW used not only d6 but other dice as well, hope they won't be needed anymore.
