Is there any information if FFG will release additional expansions for BSG in the future?

I am asking because I am building a custom storage solution and need to know if I need some extra space for any upcoming expansions?
I have the base game and all available expansions in a wooden box and it is already cramped with stuff. So I might have to buy a bigger one.

Seems doubtful. The fleet made it to Earth; what else is there? As it is, FFG took a long time just making the last expansion, and it seemed that might never happen. But FFG is also tight-lipped when it comes to what they're up to, so no one here is likely to know/disclose the truth.

I'd love to see an expansion to play out the entire journey - a set of rules to link all the four games. With a little additional stuff of course

There are so many side campaigns you can play inside each expansion, I don't see us needing an expansion anytime soon.

But they could make some print to play expansions like they do for other games.

No
