Let's get the bad news out of the way: they didn't announce any new Epic or Huge expansions.
But they did share some interesting information. The Eta-2 Across Interceptor will come with a hyperspace ring to let that ship (and the Delta Aethersprite and V-wing) be placed in reserve and come into the battle later, docked to the ring. Why is this interesting? Because they said on the stream that the ring will not be Hyperspace legal OR Extended. It's for Epic Battles and scenario play only.
That's so interesting to me! Here, they have a popular ship releaseing for standard play that will come with components specifically for Epic/scenarios. I guess it's not too weird, considering the obstacle pack and munitions pack came with scenario cards.
Also, it seems the Heralds of Hope expansion is going to come with wing cards! Yes!!! (If I heard correctly, that is - my stream cut out for a few seconds right as they started talking about Epic). This is such a natural way to release these cards, rather than another Epic-specific pack that will come with components/cards for factions you may not even own.
They said this is something they plan to do going forward, sprinkling Epic/scenario/casual play content in standard expansions. I am all for it! In fact, I don't play my Resistance ships in Second Edition very much, and I already have 6 T-70s, so I talked myself out of buying Heralds of Hope. But after learning about the wing cards I am now considering picking it up after all.
