Superman Returns Sequel To Be Titled Superman Unleashed?

/Film reader Alex Litel just sent me a link to a password protected page from the official Legendary Pictures website that lists "Superman Unleashed" as one of their upcoming films in development. The temporary plot synopsis included follows:

"Ramping up the action of its esteemed predecessor, the sequel to 'Superman Returns' promises to raise the stakes and take the audience to heights of action that no other superhero movie can achieve."

So there you have it... Legendary Pictures, Warner Bros and DC are still working on a Superman Returns sequel, and not a complete reboot. The film will not be titled The Man of Steel, but instead Superman Unleashed.

One of my other sources claims that the title is just a working title and they are still hearing pitches from different writers.

Update: After publication of this story, the information has since been removed from the Legendary Pictures website.Update 2: I want to give full credit for this scoop to Alex Litel. I made the mistake of thinking his email submission was just a reader sending in a scoop, but the fact of the matter is that he wrote about this on his personal blog first and defintiely deserves the credit for finding it.
