Re: Dany
I actually think this will feature more prominently in the show than the book. As we've seen with Robb, the show puts more emphasis on the happenings of the main characters than anything. The show will almost certainly have Dany doing something in every episode, maybe except for one or two, throughout the next two seasons. Dragons are a huge part of why people watch.
And how many Dany chapters were there really in SoS? Astapor two (looking at the slaves, killing the slavers), four for Yunhai (arrival, meeting with the merc commanders, Daario in the night, battle outcome), four for Mereen (arrival/explanation, single combat, explaining the sewers, outcome), and maybe a couple setup and explanation of the butcher king, Jorah's betrayal, her people dying on the march, sex with Irri etc. That's twelve or so ... and we are looking at 20 episodes for seasons 3+4. Do you think that Dany will only be in every other episode going forward?
So I think we will get a treatment of what's going on over there. As to whether you get the full social/political nature of everything ... probably not, but I will bet they mention the butcher king and her freed slaves dying since that is a main motivation for her staying in Mereen. I thought they did an OK job of contrasting Joffery vs. Maergery in King's Landing, and if anything they will spend relatively more time on Dany.
