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 :(

Disney is competant at delivering movies, but completely fails with video games. If movie studios were smart they'd get into game publishing; Warner Bros did so years ago, and have since brought us the Arkham games.
