Sounds like a Rebellion/Rome: Total War hybrid.As players build, manage and progress their space and ground-based units, troops and vehicles, memorable Star Wars hero characters will begin playing a role in key situations. In addition to the single player campaign mode, the game will include a two-player Empire vs. Rebellion mode and up to eight player online skirmish modes.

Another attempt at an RTS by LucasArts. Will one finally succeed? Who knows.
