I think Christian Bale said he wouldn't do the movies anymore if they put Robin in...so Robin seems unlikely.
I think Penguin is the most likely. In the Dark Knight they already introduced us to the mayor (Richard Alpert? When did you find time to be mayor of Gotham? Get back to the island!). Penguin's arena was politics, so it's possible they will have Penguin take power from the current mayor in the third movie.
If the writers have any sense at all, they'll skip Riddler this time. His character is just too similar to that of the Joker's. I think we need a cool-down period before plunging back into that kind of mania.
I vote we leave Harley Quinn out, personally. It's too complicated to have her and nothave the Joker. Your only options are to have another actor play him (over my dead body) or have him not actually appear personally. Which is just lame.
