You know what is really scary? I have a feeling that this reboot is going to become a trilogy. We'll have the next film (which hopfully will rock) and then the third one in 2012. What I have a feeling will happen is that Superboy will essentially step into his father's shoes as the new hero of earth. Of course this really could only happen is if Superman dies. If that were to happen, believe me, I will be balling my eyes out.
And I can see that happening. Richard is a good character and obviously a loving father. Superman was raised by human parents, and superboy might too. Having Superman die (heoroically of course) will end the love triangle and give superboy the chance to grow up and take on his assumed role.

This, is just idle speculation on my part, but I can see the story going in this direction if need be. It would be gut wrenching to watch though. But we need good gut wrenching movies now and again.
