I think judging from the 3rd trailer, his strength is going to be similiar to Superman Returns - You see him jump under a big steel structure bracing it up with his hands, then the next scene it jumps to his facial expressions and it looks like his struggling to hold it. Also, when you get a quick glimpse of him being thrown into a bank vault he then falls to his feet. So it looks like whatever throws him into the vault stuns him alittle bit. I think the stength and the power principles in Superman Returns we're spot on. Although, I don't believe any superhero should beable to move land mass.
