I hadn't kept up with Factorio much over the last little while but I've always appreciated how great the Friday Facts are.
Not surprised by the overall theme of the expansion but I didn't expect a different tech tree for "dlc playthroughs". I think if it's reshuffled correctly, it could really help give even the initial part of a playthrough a fresh feel and change up some of my usual strategies. Looking forward to reading about more of the details over the next year.
