I'm not sure how or when this stuff will be retconned again. The main reason for the entire reboot is the Superman lawsuit. So, DC is changing Superman. I don't think his origin will be the same as has been all these years, the S-shield is different, some rumors that his abilities are somehow weakened/gone and the reason for the armored look of the costume is to help his with that loss.
It's odd. Not sure that I like where this is going, but in the end its the same old crap. I do not like the idea of 4.99 for a comic w/digital download. That is obscene.
My understanding of the Superman situation is the Siegel & Shuster estates would gain the rights to the name Superman, and the
original likeness. Notice the S is in a triangle and not a diamond.
And thus they would own the original powers. Remember originally Superman couldn't fly, and didn't have the heat vision, freeze breath, etc.... This would be the "more powerful than a locomotive, faster than a speeding bullet, able to leap tall buildings in a single bound" Superman.
DC would own the modern look, and presumably the look of the George Perez picture
Notice the "red underpants" look is gone (thank God), and the S is a little more stylized. I still think there will be some sort of settlement that will keep Supes in the DC Universe, but that's just me. Still, a guy that looks like Superman without the names "Superman", "Clark Kent", "Lois Lane", "Krypton", etc.... will be a tough pill to swallow.
