If you take all the information from the recent interviews we can start to gather how the game may turn out. In Recent interviews on 2nd from IGN, 1UP, Ten Ton hammer, Gamespot and others they say..
* Its fast paced (Almost Console Speed)
* Graphics are great and smooth
* The interface seems standardised. Hot keys on a UI Bar.
* No Auto Attack
* Full Voice overs for all NPC, Companions and some extent our characters (There is a mention in one of the reviews about some text, maybe just during the selection, it was not too clear.)
* Loot seems to be based on Light/Darkside as well as class.
* Choices in Flashpoints can change the course of the instance. Kill a NPC and 'A' happens.. do not kill and 'B' happens.
* Flashpoints can be done solo or grouped.
* Group decisions in Flashpoints (Its mentioned that BW are still working on how to apply LS/DS points depending on outcome).
* The voiceovers seem to be done by good actors not Fred the Cleaner (If anyone has played Culling of Strath in WoW 3rd boss, you will know what I mean)
* Special moves seem to require points similar to Rogue in WoW.
* Players seem to be able to take on 1 to 4 NPCs at the same time.
* Bounty Hunters start on Hutta
* Smuggler starts on Ord Mantell
* Combat seems to be more fluid (not too sure what they were refering to by maybe queuing moves?)
* Player Characters have some intresting moves.. Smuggler (knee NPC in nuts and shoot them in the head)
* Duel use of Lightsabers shown.
* PvP, Crafting, Raiding etc all in game.
All this gained from reading several of the recent interviews.
It Seems to be shaping up nicely.
