Only briefly skimmed this thread because it was winding me up a bit. I'm definitely not a fan boy but it's clear to me that ASOIAF is NOT just a cash cow for Martin to milk. If you want to see an example of that, look at Feist. The original series - Magician, a Darkness at Sethanon and Silver something or other? - was a great fantasy series. Now we're about 50 books down the line and it's very diluted.
ASOIAF was always better (although it's not really a fair comparison, they are very different books) but if there is one criticism you can't level at GRRM it's rushing out thin books just to get them into circulation and get some cash. Stuff like the maps etc, that's what they are for. ASOIAF is precious to him, if it was about the money we'd have seen ten or twelve of them by now. He won't change them to please the producers of the show (since when has he ever given a damn about pleasing anyone??) although parts of the show may influence him in ways he hadn't forseen, that's just natural.
Now I'll be completely honest, I was pretty disappointed in AFFC and ADWD, but no way in hell would I ever say that it's because the books are just a cash cow to him now. That's just patently untrue. My biggest criticism would be to say stop working on maps and playing cards and goddamn recipe books that no one gives a crap about just to get in a few quid and concentrate on your legacy. However, I appreciate it it's not my place to tell him what to do, so it would be friendly advice
