Player vs Player action is hinted at too and can take place in a special Battle Zone, like the planet Alderaan. No release date for the MMO yet.
It was pondered how BioWare would let players get from one planet to another, though private starships were believed to be high on the list. The Old Republic is based off Knights of the Old Republic which featured the Ebon Hawk starship - your transport.
It was also a hub for certain other functions too and will likely be the same for the Star Wars MMO; crafting items, chatting with companions etc. A new pre-rendered trailer has aired from E3 2010 showing some Republic vs Sith action on Alderaan.
It seems the perfect tease for the grandeur of these Battle Zones that BioWare have planned. The clip also has some Jedi kicking rear for a change…
