New power for Superman?

The Superman Homepage has discovered that Superman will soon sport a new super-power or powers, as well as have a change in his personality.
Apparently the traditional Superman will be soon be gone, replaced by one that's more up with the times.
The Homepage also states that the new power may revolve around Photosynthesis and come to (sun) light in July issues.
Superman has had some new powers before, like in the Christopher Reeve movies, where he instantly repairs the Wall of China and also can emit forces from his fingers.
In the comics, he's had temporary new powers and also changed to become an energy being for a time.
Some of Superman's current powers, like super-speed are already very under utilized in the comic books, so is adding powers a good idea?
Regarding a personality change, are we talking about making him less of a boy scout and more like Batman or what?
