I heard the main reason they were rebooting the DCU was to make Superman more relevant.

That wanted him as the first superhero again; so the JSA is gone.

They also didn't want him tied down to Lois anymore.

It also seems like they've used the reboot as a vehicle for bringing Vertigo and Wildstorm into the regular DCU.

A lot of everything else is staying the same; Batman, Green Lantern, Flash, Aquaman, etc. are all picking up right where they left off.

This is what I've "heard", I'm not claiming to be in the know or that I posses any insider knowledge.

Time will tell how the whole thing actually plays out.
