....thats another thing,....how come we didn't see any different versions of Astromech other than R2 units with different heads in the prequels.

http://www.angelfire.com/droid/astromechs/page4.html

Flip!.....never seen some of those images before

The R1,....similar to the droid the Jawas tried to sell

....but still no previous designs of R2 units (apart from the droid in the bath, which just looks like a dome painted in the style of a R2,...cheaply done)....

Nearly all the images in that link are all the traditional OT R2 units painted in different colours,....no design to indicate an evolution of previous models, like what is being done in the new film & in Rebels
