Ehhh, full voice-acting isn't so innovative, especially since Bioware is the creator of the KOTOR series. It's at best a very modest evolution, and I think the OP wasn't denigrating the game so much as thinking about what a revolutionary MMO would be.
But Star Wars as such an expensive franchise couldn't afford to gamble on something too revolutionary. It'd devastate EA if they had tried something way outside the box and it failed. The next big thing will probably come from a smaller developer, or one with a cheaper (or new) franchise to work with instead of Star Wars, which must cost a fortune to license.
