Just a thought, I don't believe all the Horcruxes have been accounted for, so I can see Tommy-boy returning yet again. On the other hand, the demise of this version seems to have removed 'most all of his marked supporters and radically reduced the attraction he has, so I can see where he'll have a rather more difficult time when he does return; this will also give thePotter trio more time to get used to each other and what their bond enables them to do.
