German MMO fansite "buffed.de" had two long interview with Chilton at Gamescon in Cologne.
The second part has two very interesting informations:

"Johann Trasch: Also gibt's vielleicht nur zwei Raid-Tiers und eine neue Erweiterung nach einem, eineinhalb Jahren?
Tom Chilton: Jap. In der Theorie. Die Praxis könnte anders aussehen."
translation:
"Johan Trasch: So maybe only two Raid-Tiers and a new Expansion after one, one and a half year?
Tom Chilton: Yep, In theorie. In practice this could look different"
I hope they will release the video of the interview soon, right now I only found the translated version.
So we get an Oger Raid with Orc flavour and then an Orc raid with Legion flavour...
He also mentioned that we will see Kairoz again.
When asked about the other legendary beside the legendary ring he said that Gorehowl could become a legendary 2 hand weapon for players and that Teron'gor is also a possiblity.
