TWoW not being out until post season 5 means it will almost be years after the show is over until we get ADoS.
S5 - Spring 2015
TWoW - Fall 2015/Spring 2016/Summer 2016 (?)
S6 - Spring 2016
S7 - Spring 2017 (final season?)
S8 - Spring 2018 (if they decide they need one more)
ADoS - Who knows, although GRRM won't have to do press/attend events for the show anymore so maybe he'll get more work done once the show ends. So, 2019? Maybe?
Unless George pulls a rabbit out of his hat, the show will end years before the books. (plus, GRRM hasn't ruled out an eighth book as far as I know...) Which is inevitable, even if TWoW were to release tomorrow, but
Really wish they would just do most of AFFC and ADWD and extend the contracts, its not like hey can't afford to as they'd still make retard levels of profit off the show, it would simply amount to less profit. Also the streaming service might change the actual amount of $$ they receive per viewer which may make them change their calculus.
I maintain that D&D shouldn't try to get there any sooner than they have to. There's a whole bunch of stuff they have (seemingly. we don't know what all made it in yet) cut from AFFC/ADWD that would have been great to see on the show. If what we think was cut was cut, then it could have contributed up to at least one whole season's worth of content just by itself.
