It's taken George R R Martin many, many years to produce the next book in A Song Of Ice and Fire. He's blown though promised deadlines with experienced ease, and I totally support the speed at which he's working, because that's how it fucking works. It'll come out when it comes out.
But at least that long, long delay means I never run out of theory videos and essays to gorge on. I have wasted vast amounts of my life happily watching and reading these fucking things, spending hours on fuckin' Patchface and his freaky shit.
And even if they're years and years old, they're still valid. The TV show spoiled a lot of stuff, but veered off from the books right from the start (because they're two different things) and there are all sorts of theories about Hightowers and Blackfyres and Manderlys that haven't had any further resolution in a decade.
I highly doubt I'm going to run out of them, because at least 27 new ASOIAF theory videos are uploaded every second. And I don't have a lot of faith that the next book is coming anytime soon, so there's always something to fill the gap, and it's all as tasty as a Frey pie.
