It appears that gamers are demanding the future of the expansion to include more casual gamer content over hardcore gamer content. Most may disagree with this, but check our Blizzard's standpoint here.

I'm a little disappointed that people criticize us as not doing things for the casual gamer. The whole basis of our design philosophy has been to create a game that appeals to players both casual and hardcore. The very fact that players who vehemently call themselves "casual" reach level 60 in our game (have max tradeskills, have epic mounts) seems like a testament to me that we achieved that goal (at least somewhat).

In fact, we often prioritized things in favor over the hardcore. For those of you who have been playing the game since release, you'll remember that the game shipped with Onyxia and Molten Core as our only raid content. Rather than rushing to get Blackwing Lair, ZG or AQ done, we then focused our attention on Maraudon and Dire Maul. We prioritized those two dungeons OVER raid content even though we were lacking in the latter department, because we wanted to fully flesh out our casual experience first.
