Basically, before LucasArts got shut down, they were working on three projects, First Assault, 1313, and something else that was simply known as "Version Two". The footage in the link is from Version Two, and it looked very Battlefront-y, and it is not First Assault, as that didn't have vehicles.
It looked really good too :(

I more disappointed that Star Wars 1313 got cancelled. The gameplay looked so good. It makes no sense why they would cancel a game that's practically finished. They would have made millions from it.
