So they've finally stopped waffling and said, yes, 7 seasons total.
And they told us that, after this season, they'll have caught up with stupid George Martin. Apparently there's been a meeting where lazy fuckwad Martin just outlined what happens to the producers, so now the show doesn't have to stall for his idiot ass.
Which means...all that time everyone has invested in reading and waiting for the book series has just been wasted!
