I wrote about this just a few days ago but the new trailer reinforces the notion: In the new Superman movie, Krypton, Kal-El's homeworld, lives. It doesn't blow up. 

Earlier evidence:

1. “I’ll be honest with you, there’s no Kryptonite in the movie,” says director Zack Snyder. (Source: Entertainment Weekly cover story.)
2. “This film reveals that even on Krypton, young Kal-El was a special child, whose birth was cause for alarm on his home planet.” Which gives Jor-El a reason, besides the destruction of Krypton, to send his baby son away in a rocket ship. (Source: Entertainment Weekly cover story.) 
3. In “Superman II” Gen. Zod tried to take over the Earth, since there was no longer a Krypton to take over. In the new teaser, he doesn't try to take over Earth. He simply asks for Kal-El back. But back where? (Source: “Man of Steel” teaser.)
4. Zod also refers to Kal-El as “one of my citizens.” But citizen of what? (Source: “Man of Steel” teaser.)

And now we have the new trailer, trailer #3, in which:

1. We see a battle on Krypton.
2. We see Zod berating a woman thus: “You believe your son is safe?!” It's obviously Lara he's talking to. But how? Isn't this after Kal-El is shot into space? And isn't that generally when Krypton blows up? Yet there they are, talking.
3. We see Zod shouting, “I will find him!” amdist a Kryptonian backdrop.

This trailer, by the way, is the one that most recalls “Superman: The Movie”: from the dialgoue between Jor-El and Lara about their child's place on Earth, to Lois naming Kal-El, from the S-like Kryptonian symbol on his chest, “Superman.”

Am I missing something? I just can't get around Zod extracting Kal-El from Earth rather than battling him for it. The only reason you don't battle someone for a planet is if you already have one.

That's Jor-El. But that doesn't seem like a planet blowing up. It seems like soneone's attacking.

And this is Zod yelling, “I will find him!” Seems like the same place. Seems like Krypton.
