Dungrollin:
I've noticed a lot of people suggesting that Harry won't return to 
school, but that Ron and Hermione will. Given their insistence at the 
end of HBP that they're with him for the long haul, I'm surprised so 
many think that they'll change their minds, and I'm curious as to why.

Is it because two of the pieces of cover art show them in robes while 
Harry's in muggle clothes, or is there another clue that I've missed? 
Any thoughts gratefully received.
