Another bit of information that I found interesting- we *WILL* hear about the POVs who will not have front stage as it were, but will have it in ADwD. The reports of those chars will be somewhat garbled and messy as can be expected from any news that has travelled that distance and is that important. ex) Varys' manipulation of the Dany information, or Theon's skinning of the miller's information (we didn't know it wasn't Bran and Rickon until later). *THOSE* are the kind of reports we will see in AFFC about the missing POVs. We will get information on them, but have no idea which parts, if any, are correct.
I have some more things to add about things I asked, but I will probably trickle out things as I sober up and recall them. :p
Bran will have one or two chapters in ADwD, where otherwise he would have been left out of the what would have been the fourth book entirely. He remains one of the most difficult POVs to write due to his youth, crippled status and the magic.
[Note: Description of a spoilerish question regarding unreliable narrators removed. GRRM laughed at the question and gave no answer.]
He did skillfully change the convo to conversation about what would be one of the most fun unreliable narrarators in history- Aegon IV The Unworthy's POV. He sounded very interested and determinded to do a novel about that VERY interesting char. I would beat you all down with a stick to be able to read it.
