They gave a brief summary of the technical progress S42 has made, but they made no mention on the actual story content.
Last time I checked, Chris Roberts said that the story would be about 20 hours long. Given how rich the SC universe has been shaping up to be, I'd be incredibly disappointed if RSI neglected to focus on telling a comprehensive singleplayer story within it. 20 hours is way,
way too short; you can't possibly expect to develop more than a brief pass at a couple planets at most, let alone tell compelling character arcs for anyone else besides the main character(s) (probably Mark Hamil's character, if he isn't a disposable mentor character that is). I know they said they weren't going to talk about the big spoilers, but come on man; tell us what the actual singleplayer campaign details outside of "blow up Vanduul with AI squadmates". Who are the characters? Which worlds are we going to explore? How in depth will the civilizations of these worlds be explored? What about the politics of the Imperium? Will the story take time to breathe and give us a decent amount of time to explore in between missions and get a feel for life inside the Imperium and inside the navy? Will we get to form relationships with the crew members of the Idris the squadron is based on, or will they just be nameless workman NPCs in the background? Will the antagonists be characterized beyond just being generic aliens you shoot?
It'll be a massive shame if it's just another tacked on singeplayer campaign like the CoD and Halo games.
