Blizzard sent us the first image of Thunder Isle, next raid dungeon for 5.2, coming January!

If you squint your eyes really hard, you can almost spot hours and hours of trash mobs. But hey, if they give us a kara-quality dungeon, I'll do an hour of trash for each boss happily. I love the openness of Kara. It feels like a mansion/tower that actually has stuff other than the bosses in it. There's multiple ways to travel throughout the tower and stuff that doesn't have to be seen. you can explore that place which is something that I've not really found to be true in 99% of other dungeons. everything else (even ulduar) is just so linear. BRD was the closest to that feeling that I know of.
