From the Q&A session at SW: Celebration today.
Edit: I didn't catch the complete answer from the panel, but I believe more digital content coming for Campaign. Which is great!
If anybody transcribed the full answer, post it below and I'll edit my post to include it.
Edit 2: Thanks @jeffculligan & @maddwarfer for transcribing the whole response:
Edited by cnemmickQuote"We have a couple new things coming up for the app relatively soon that are going to be cooperative, kinda cooperative challenge-based maps, where the idea is you play through them as a group, and you receive a score at the end based on how you performed, so that you can replay them and try to get a better score. Those are a couple things that we currently have in the hopper right now for Imperial Assault. So as you can see, in the past year we almost exclusively focused all of our efforts on just making that app better and the cooperative experience better."
<Questioner pushed for an answer on physical products>
"We currently have nothing additional planned as a physical product for Imperial Assault. But that line obviously has approximately 60 physical products in it, so there's a wealth of content there, and a lot of the campaigns that we released as 1-vs-many campaigns, you can now play fully cooperative through the app as well. So there's a lot of opportunity to go back and revisit some of that material. At this moment we don't have any plans for additional physical products for Imperial Assault."
Added that digital content is coming for Campaign
