The flash event description seems to me to indicate that we will use Ewoks against Empire, Bounty Hunters, and Droids. No word on other requirements for those events, but it sure sounds like we will be using Ewoks. We probably won't know anything like star requirements until very close to when it's live if they do it like Luke and Phoenix. And we might not have full details on all the aspects of that until it's live (e.g. we didn't know about what was and wasn't required for Luke and the Jawas until it was live, and we didn't know which characters were on which tiers for Phoenix ahead of time).
