It looks like things are picking up for Season 2 of Discovery with some casting announcements coming out in the last few days.
Anson Mount (who formerly co-starred with Miles O'Brien himself, Colm Meaney, on the Calgary-shot Hell on Wheels) has been cast to play Captain Pike.

Also, comedian Tig Notaro has been cast as the chief engineer of a ship named the USS Hiawatha.
The extent of either of these roles is unknown for now. They might be series regulars, or they might not amount to more than a one-episode guest appearance.
