After reading the mined progress steps on the Dark Heart of Pandaria, do you think it is possible that the next tier will revolve around Old Gods and the like, a'la Ulduar? If so, I personally hope that they theme the art style and lore around more the traditional Lovecraftian concepts. This current tier seems absolutely awesome (haven't seen most of it), but Ulduar remains my favourite raid, and I hope they can capture the menace that Yogg Saron represented.
Having said this, YS was indeed more central to the lore and plot of WoTLK than any OG has to do with MoP, so I understand nothing of the sort transpires.
Thoughts?
