Yes indeed, I think that this is a shift back towards some use of AoE on fights, but I think only on boss fights. Encounters like Magmaw are such that a fairly junior raiding guild will have a hell of a time with his maggots. I know for a fact that without at least 60% of our DPS being ranged on that fight, we can't beat it, though we are only JUST getting into raiding. It is my belief that some of these AoE buffs will be scaled back if people are finding ZA and ZG too easy, and if tanks are finding the quickest way to down a pull is to just grab everything and depend on AoE's as was the Wrath style.

Honestly, AoE should only be for grouped-up adds like Magmaw's larva, and trash pulls with more than five targets. Any other situation should be single-target DpS, with CC's on each pull. Personally, I kinda hope Blizzard buffs up the current heroics, if in numbers if nothing else, to match the standards of newer heroics. Though, seeing as people would bitch about harder dungeons and blizzard has already divided heroics into teirs, that's not likely to happen.
