Someone at DICE did a Q&A on twitter ( https://twitter.com/EAStarWars ), he shared many information :
- The game will use its own ingame server browser ( no battlelog? )
- More Heroes to come
- Customizable characters to a certain extend
- Unlocks and collectibles system
- No MAC version planned
- Millenium Falcon and Slave 1 playable ( to be confirmed, but they will be in the game for sure )
