Also we know that Sidious is on Coruscant...
I don't think this is meant to be a huge secret secret. The enormous hint at the end of TPM of panning over him as they talk of the Sith was a clear indication. I think it is meant to be something that WE know, but the heroes don't, thus increasing the sense of tragedy.
Yet I managed to miss that close up twice at the cinema...damn that popcorn.
Also, there was that lost scene where Maul made contact with Sidious after he'd failed to get the queen on Tatooine. Sidious told him not to pursue, because they would come to him. Apparently it was omitted (don't know whether it was filmed) because it was too strong a hint at Sidious' identity.
well he is Darth Sidious who else would Palpatine be in Star Wars? I mean last night at Nighty.net forum they said they have different Height and they said Darth Sidious is taller then Palpatine. I cxan't belive that i eman tehy have to be the same persoon. I mean it would suck if they were 2 diffent people. I think they are the same. 馃槑
