We probably would never make a non-English speaking player race. I know it seems attractive, but simply put, hearing alien for way too long drives you crazy. An early build of the game had Tython populated by a race other than Twi'leks, and after about the fourth quest, you want to put a fist through your monitor.
So any races we add in the future will need to plausibly be able to speak basic.
Reluctantly, I have to agree. It's nice to have for flavor every now and then, but when I talk to too many alien language NPCs in a short time period, I have to spacebar through it. Maybe if they made it as complex and natural as an actual language it wouldn't be as bad, but you start to realize that you're hearing a lot of the same words over and over. And don't get me started on talking to Bowdaar. I actually freaked out some of the people in my house with that.
