I've been told the SW will not get a new codex, but an expansion book - I guess similar to the last Tau update. There will be new models, but I have no details about them (yet).

Logan Grimnar has a kit of his own. There are bits for Björn in the SW Cybot kit. Same for the Swarmlord in the Swarm Tyrant kit.

But so far it's mainly a WHF thing.
