The way I see it is that Jason Bateman wouldn't have got our hopes up by talking about it while promoting Juno if he didn't think it was a high possibility. Here's hoping, anyway.

Lavender? Is she new? I'm assuming she gets all up on Ron? lol. I've heard about the outcome of the books and, from the films anyway, I never really got the impression that Ron and Hermione would like each other. Same with Harry and Ginny. They are rarely even in the SAME ROOM! lol. Of course, the books could be more detailed.
