Maybe they'll follow the example Batman set and just call this The Man Of Steel.
Singer says he plans to get all Wrath Of Khan with this film, and put more action in, something missing from Returns. There is a terrible, threatening element of foreboding, possibly the return of General Zod (Superman II: The Wrath Of Zod?)
We also want to know what happens with Superman's son Jason, something put into the last film that was not in the script or the film's novelisation.
As long as we don't see him end up in a Superboy costume.
