In the Clone Wars they seemed to have made the Probe Droids on that a lot more smaller and mobile not to mention the SE droids flying around Mos Eisley being smaller too. I wonder if tying the Saga together, should those Probe Droids in Empire be shrunk down as well? Mind you it would be quite a challenge for Han to shoot the thing if it's smaller and quicker though.
As for a grand reveal of Palpatine in his throne room with prior holographic transmissions, I'm all for it! :-)
