Since its today I guess I can post this info:
Yes its Badab War, it will be in 2 books (both around the size of Tauros) and there are rules for ship fighting.
You have seen all the MK's of Power Armour and Weapons
New Red Scorp Librarian and Honour Guard
Huron Blackheart in Terminator Armour before his face got melted
Space Sharks, though they have been given a Greek name to sound less cheesy.
Loads of chapter specific shoulder pads (both power and terminator) including Mantis Warriors - which have been developed both fluff and rules wise (lots of scouts I believe).
I'm sure this will all come out today to back me up.
