A Reading with GRRM (Worldcon, Philadelphia, PA)

GRRM also revealed that aFoC will hopefully span the next 5/6 years so that aDwD can begin where he expected it to do so all along.

He also heavily suggested that characters that will spend their time learning in the next 5/6 years will not feature very much in the next book. But all current POVs will appear. So one can assume that we wouldn't get more than one or two Arya/Bran chapters.
