You forgot Draco and his escape (or not) from a pack of Death Eaters, and his likely (I think) alliance with Snape in whichever way Snape is going to go in the end.

I do wonder why Voldemort would bother sending Draco to do something expecting him to fail. Maybe he figured if he failed, that's one incompetent wannabe DE out of the way, and if he succeeded, bonus.

I think we can skip the Quidditch. I was just looking at an interview with JKR where she said she's written her last match.
