I think the BattleMech manual was pretty close to being done, so I would imagine it ought to be out next. As much as I want to see ilClan, I don't think there has been enough hype to suggest it is coming up next.
We don't know where CM: Davion is at the moment. I believe the last thing Ray mentioned was that it was waiting on some particular task to get finished up that wasn't ready when expected. So, it wasn't so much a case of, 'We decided to delay CM: Davion,' as it was, 'CM: Davion has managed to delay its self!'
