It says under Bel Iblis' description in one of the screenshots that he "stole the Gargantuan battle platform from an Imperial testing facility". Does that sound like the Rebels are getting a new (possibly stationary) space unit?
Also, it looks like the ground maps are getting even more enhancements than infantry-specific terrain. Terrain height also seems to be a factor now, adding range to units stationed atop hills. Sounds good to me.
