What is BATMAN: HIDDEN TREASURES?

From what I have gathered DC is is putting out yet another Batman solicit.  Apparently DC has Wolverine envy.

Ron Marz is apparently writing the story and Bernie Wrightson is doing the art.  Other than that, I am confused as what plot direction this book will utilize as it relates to the Batman universe.  Is it Bruce Wayne?  Is it Dick Grayson?  Is it an Elseworld Tale?  Is it set in DC Universe continuity?

If any has any answers it would be much appreciated.  I guess I am just overwhelmed (or underwhelmed) depending on the day.  DETECTIVE COMICS, BATMAN, BATMAN: RETURN OF BRUCE WAYNE, BATMAN: LONG ROAD HOME, SUPERMAN/BATMAN, BATMAN BEYOND, BATMAN AND ROBIN, BATMAN INC., and RED ROBIN to name a few.  It's a lot to keep track of as a Batman fan.

THeseare some pages from BATMAN: HIDDEN TREASURES. Any help?
