Yep. That's the general theory so popular and makes enough sense that in a way, I'll be both pleased (for picking up on it) and disappointed (for lack of surprise) if it really turns out that way.

At the same time, it would be sort of lame if GRRM decided "well, everyone figured out R+L=J and the three headed dragon and all so I guess I better change some things around".

Then I just get a little bit bummed out (and guilty for feeling entitled) that the next book probably won't be out for a while still.
