By the time of Episode 7, I think it would make sense for R2D2 to have an upgrade that would allow him to speak English. Battle droids spoke English, so we know it's possibe for robots to do it. Imagine how cool it would be if the first time we hear R2 in Episode 7, it's like this: Luke: "Artoo! Power up the ship! We have to get out of here!" (audience expects familiar beeps) Artoo: "Roger roger!" (audience's jaws all drop and everyone high-fives each other!) Does anyone else like this idea, or does everyone think Artoo should continue to just boop and beep?
