Ron/ Hermione romance will contunie. They will be together with Harry as they won't let him go alone. I think that the main romance in book 7 will be R/Hr. We won't see H/G. Harry will be busy and won't give Ginny the chance to go with him so he must step aside from her until he can manage to kill Voldemort and this won't happen until the end of the book ( I think that in all his journeys to find and destroy the Horocrux, he will think in Ginny some times. He will miss her so much because Harry can love powerfully ) But Rowling said that we will see how Ginny is powerful in book 7, I think she will help Harry by the power of her love. They both love each other. I hope to see a happy ending in this book. We saw the sad end in book 6 so Jo should give us a break Bill and Fleur will marry. Tonks and Lupin will fight together and I believe one of them will die ( The little voice in my head says so ). I don't see any of N/L romance in book 7. They are only friends as I think.
