I'm pretty sure that Bagman will be back in the next Potter book.
He flight at the end of GoF like Karkaroff did. I assume that Dumbledore try to make Karkaroff come back but Dumbledore will catch bagman and will be offering him a lot of money. Harry trusts him and so he can make him go near of Voldemort with a portkey or something. He could be the next Dada teacher and be very close to Harry.
"When the eigthieth months dies, Bagman will be back and he will know things the white lord knows not." It is my new prophecy, do you like it.

Yeah, somehow I doubt a prophecy would name Bagman...or ever care about him.
I think he'll be back 7th book...along with everyone else JKR ever wrote in.

Hmm... didn't even notice he wasn't in book 5..

What's wrong with this picture?

I can't see Bagman teaching DADA. He seems a bit too stupid and he would probably find a job as a teacher too boring.

...not the DADA teacher but maybe quidditch teacher or coach. There must be a reason that we found out that he played for the wasps and for england...having said that I don't really think it is because he is going to teach at hogwarts.

I could see him being a Quidditch coach if Hooch died and Krum was unavailable, but I don't see him as a teacher. As for DADA, I think they need to get a GOOD female instructor for once. Think about it. First year, you have Quirrel, who though evil was sort of pitied until you found out about Voldey on the back of his head. In the second book, you had Lockhart, who while conceited had a fan base in the BOOK (not reality). In the third book, you have Lupin- loved by almost everybody. Fourth book, you have Moody, who seemed really cool until you heard he was Crouch...but until that point, he was fairly liked. So you have a history of male teachers that all have some positive attributes before we learn their true nature (except Lockhart- but he was funny with how the other teachers played him). Then we get the ONE female DADA teacher...and she's a complete bitch. We need at least one female in that position who isn't completely incompetent.
