Fans of Star Wars: Battlefront II will be able to play as the 41st Elite Corps And 327th Star Corps starting on August 29th. EA stated "Purchase price will be released at time of availability". Hopefully you will be able to use earned credits and not have to pay cash for them, unless you prefer.
Also EA mentioned that the Palace Hangar on Naboo Map is now available in Blast and Custom Arcade. I have been playing blast for the past week and have yet to see this map in rotation.
One last thing, if you liked Ewok Hunt it has now become a permanent mode.
