1) He said that there will be fewer songs per episode.
This is such a mistake. We are hopping mad. It's hard enough to get our favorite singers doing enough songs already when they are split up between everyone on the show. Why does Ryan Murphy think we watch Glee? It's not for the plot or the characters. It's for the music. And sometimes the one-liners.
2) He said that there will be no guest stars except for one tribute episode that he's been working on getting for a while.
Ok, we will accept that. Getting rid of the flashy guest star episodes can only help the show.
3) He said that the seniors on the show will graduate. Unless they are pulling straight Fs, like Brittany. There will be lots of new kid characters to ease us in.
Good luck getting us to buy those soundtracks if Rachel leaves the school .... When asked if they could graduate but stay on the show, he said, "I don't think I like that idea."
