Superman Villain Revealed?

So all that talk about the Superman reboot's new female character? The latest report on the matter would seem to indicate that the gal is actually a villain in the film.
Alice Eve (She's Out of your League), Diane Kruger (Inglourious Basterds) and Rosamund Pike (Die Another Day) were all reported this week to be up for the role. And now Latino Review has the scoop that "The character these lovely actresses have come out for is none other than a Kryptonian villainess who is going by the name of URSA." Sound familiar?
Ursa, of course, was General Zod's right-hand woman in Superman II. Does this mean Zod, too, will show up to battle the Man of Steel?
The site also adds that despite the fevered fanboy speculation to the contrary, Lois Lane in fact is in the reboot as well.
