The first tier of Cata was essentially tBC style gaming. People bitched about it so much that they changed it.
I very, very seriously doubt that we have much credibility in Blizzards eyes in terms of "What we think we want" these days as a result.
As for a "Massive outcry", there is no larger a cry than there ever was - which is very small. There is more complaining about the "good old days of WotLK" than a cry for a return to Outland.
