You know, about the little part JKR said about HBP being like the 
first part of one book...


So - I think it may be that - after his shortest stay ever (leaving 
before the morning of 31st July; could be midnight as well) - Harry's 
NOT going back to them until the end (or the middle) of 7th book, 
when he defeats them. He could use Veritaserum or Legilimency or both 
to get Aunt Petunia to tell him all he needs to know... and then he 
leaves them and never looks back.
