Kids love Superman, Batman and the Hulk too. Their relaunches struggled. You're not taking into account how bad the marketing for TAS has been, its mixed reaction and the fact they're starting everything over after the ill-received Spider-Man 3. Those factors will hurt its box-office. At the most...$225M and if the 3D bump really helps (which it doesn't always See Wrath of the Titans still not crossing $100M domestic and John Carter).
International? No doubt it will save Sony's bacon here.
