Question for Star Wars: Battlefront III have lots of information that may answer questions.
Utapau Sinkhole, Death Star Interior, Polis Massa, Coruscant Space Battle, Coruscant Jedi Temple, Yavin Space Battle, Kashyyyk ground battle, Death Star Ground Battle, Tantive IV Interior. Thats all I can think of for now.
Heroes and known powers/weapons: Obi-Wan Kenobi(force push), Luke Skywalker, Darth Vader(force choke), General Grievous, Mace Windu, Darth Maul, Anakin? You can also use, Palpatine(force lightning), Yoda(He's obviously going to be jumping around a lot[dont know his force power yet]), Jango Fett( Dual Blasters and Jetpack. Each Hero has a life bar that slowly ticks down. You can increase it by killing people and doing objectives.
Other: New sprint feature, Each faction has a new class, commander class, pilots are only available in space battles, technicans are used on ground battles. There's a new mode, Capture the Flag, where you have to go to the enemy hangar, get the flag, fly back to your hangar and go to the control room. You get 1 point each time you get the flag back to your hangar. New clone skins to fit episode III.
New Starships(and old):
Republic: ARC-170 Starfighter, Jedi Interceptor, V-Wing,
Theta Class Shuttle(unconfirmed)
CIS: Vulture Droid, TRI fighter, Geonosian Fighter (unconfirmed), Nemodian Shuttle (unconfirmed)
Empire: TIE-Bomber, TIE-Fighter, TIE-Interceptor, Sentinal Class Shuttle
