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 :(
