To Peter Jackson:

No.
Do not, I repeat, do not make The Hobbit a trilogy.
I can understand a two-parter; it's a deep book.
But a trilogy's just pushing it.

I respect your movie-making skills. But do this and I can guarantee you that you're going to have a lot of extremely upset people on your hands.
Yours truly included.

PS--If you really want to use that extra footage so badly, do an extended edition!
