Heir of other houses

What do you think became of the Heirs of Ravenclaw or Hufflepuff?  

They are the Switzerland of Hogwarts, never in the thick of things.  I 
wonder if their identies will be revealed and if it will play into 
things to come.  Maybe one of the ways LV may need to be killed is 
that all of the heirs have to come together to vanquish LV.  Harry of 
course is the Heir of Gryffindor.
