JK said in Naperville, IL before she was popular that the trio would live through the series. So ha.
Though that might mean till the last book...but I can be delusional if I want.
Draco seems to have more feelings for Hermione than Ginny.
And Ginny will either end up with Neville or Harry. She obviously still loves Harry and he loves her.
Ron and Hermione are obviously going to get together.
"You belong in Gryffindor,
where dwell the brave at heart,
Their daring, nerve and chivalry
set Gryffindors apart."
