one thing ive always wondered, c-3po can speak billions of languages because of the fact he's a protocol droid.. yet r2-d2 and all the other astromech droids only speak in beeps.. couldnt they just install the same langauge chip that c-3po and other protocol droids have into astromech droids, so they can still speak in beeps but also speak english/other languages to humans/other species? battle droids etc speak english... just a thought
