I don't think there has been anything official. I keep checking every now and then whats up. There is community discussion about the future and what the next expansion might contain or even Incursion 2nd edition and about kickstarting it. Personally I would love a modular board and mission generator and generally more missions with the existing 3 armies.
I agree with you on a modular board expansion with more scenarios.
No need to have any new models at this time. The present ones are so good there is no need to update them!
And yes, I am pretty sure Jim is still in business selling the game. I exchanged emails with him a few months ago about some of the miniatures, so he is on top of the activity.
All new games cool off after the first year - it takes real patience to keep a game alive in the long run. I hope Jim has that patience. It's a great game, and fills a niche no one else has in the game world.
