From the BBC : BOXING: Joe Calzaghe is to give up his WBC super-middleweight title, the BBC understands. More soon. When the full story pops up I'll put it here. This content is protected
Well if you move up in weight to the next divsion and have no plans of returning to the divison you should give up the titles
Assuming Clazghe have just a few more fights in the callendar then he will fight only big names, no more waste of time for the mandatories. First Jones, then probably Tarver/Dawson or winner of Pavlik-Abraham, maybe Taylor or Winky. He will not fight a life body at SMW untill someone else unify the titles.
