In case you haven't heard, DC Comics is relaunching all 52 of their comic books with Issue # 1's this September. That means the first ever issue of Action Comics featuring Superman since 1938. More than just a number's change, there are changes to the DC characters, namely Superman. A costume change and making him single again and not with Lois Lane.
Also, Superman's adoptive parents, Jonathan & Martha Kent are dead. It will focus more on his "Kryptonian" heritage more. Gone are his red trunks as well. It kind of looks like it is just sweats or what not without the red trunks.
As for him no longer being with Lois Lane, that is expected in a reboot. Making Superman single gives his alter ego Clark Kent more storylines, such as what Marvel Comics did with Spider-Man and his alter ego Peter Parker and his marriage to Mary Jane Watson as never happening.
DC Comics is making drastic changes to its entire line, aside from Batman. Dick Grayson took over the cowl from Bruce Wayne a couple of years ago when Bruce "died" but has not returned to the mask full-time.
The New York Post was given the cover of Action Comics #1 this morning written by Grant Morrison. It features a young Superman wearing the cape and blue jeans.-Dr.FB
