At the end of AOTC did anyone catch that Darth Sidious' hideout on Coruscant looks like a earlier version of the Imperial Palace from later on? If I remember correctly there were some pics in the Mara Jade comic and the Crimson Empire comic. I'll have to dig them up. Then again that might be considered EU lore. I don't think there was any good pics of it in any of the movie artbooks or not. But to me I thought it was a cool little hideout and it seemed like work in progress of the Imperial Palace.
