What's going to happen to Hogwarts?

[School owl]

Now that Dumbledore's gone and Snape's gone, what's going to happen to Hogwarts? Will it close? Will it stay open? If so, who will be the Headmaster/Headmistress? Who will teach D.A.D.A?

My thoughts: I think that McGonagall will be the Headmistress. I think that Hogwarts will stay open. Life goes on...
