This came up in our guild chat today, thought it was worth throwing out to the masses to chew on... With the precedent of a 4 ship unlock for Han’s Millennium Falcon set, and the Sith bomber hittin...
Capital ships is the next big focus I hope. The 'leak' would have us believe Grievous' capital is next on the board, which would probably coincide with Anakin's ship becoming farmable.

If the Ebon Hawk does arrive soon it'd be cool to see HK47 and T3M4 as copilots alongside Revan.
