Just one question: it's kinda clear that Palpatine is the master of Sith and he's at the same time working for the Republic.
So it seems both the clones army and the droids army are his weapons to get the power and create the future empire.
The clones soldiers are the same sodiers of the last episodes, I think, but where did the droids go? I don't remember the droids in Episodes 4, 5 and 6.
