Tarkin wearing the same uniform for twenty years might explain the stench though! ;)

Not having Vader in "prototype" armor modeled after McQuarrie's early concept art was a missed opportunity. Not to mention the suit looks too modern compared to the 1977 costume.

The prototype armor would have been a good idea. But Lucas clearly wanted everything to match up perfectly with the OT. So Anakin's ghost has to be Hayden. And Leia's memories of her mother, no wait what about Leia's memories of her mother? ;) I think there's been some claim that the Leia's memories thing willl be tied up in the live action show, but we all know it'll just be some messy fix patched on to fix up where George messed up. Though I'm sure we'll be told it's story Lucas had all along.
