GenCon Rumors - Star Wars: Legion

From GenCon, there is a rumor of a new game to be announced soon by Fantasy Flight Games.  The game is Star Wars: Legacy, and it is a new tabletop miniatures game with unpainted figures.

Star Wars: Legion

Epic warfare is an inescapable part of the Star Wars™ universe, and you can lead your troops to victory with Star Wars: Legion™, a two-player miniatures game of thrilling infantry battles in the Star Wars universe! As a miniatures game, Star Wars: Legion invites you to enter the ground battles of the Galactic Civil War as the commander of a unique army filled with troopers, powerful vehicles, and iconic characters. While innovative mechanics for command and control simulate the fog of war and the chaos of battle, the game’s unpainted, easily assembled figures give you a canvas to create any Star Wars army you can imagine.

If true, this may explain the recent parting ways of Games Workshop and Fantasy Flight Games, as GW is the big player in the realm of two player miniature games, (especially with 8th Edition 40K getting such a good reception).

The two biggest questions at this point are:
1) Is this rumor true, and if so, when will it be announced?
2) What scale will the miniature be?  Too small, and the individual figures will not be interesting (who wants a 6mm Luke?).  Too big (28mm), and the iconic vehicles (AT-AT) that define Star Wars warfare will be hard to incorporate into the game.

I have a number of miniature games, but hoping the rumor is true, because who wouldn't love replaying the iconic Battle of Hoth?
