Man, What a freakin bummer. This year would've been bigger than anything I think any of us could've imagined.
That would've been a potential catalyst for many great, great things for the event.
Ideally, This would be the part where this story goes to the mainstream news media, the fans go APE... Then, they (HBO) realize this could still work and the demand would be huge, go back and negotiate a bit of a better deal, silently kill graveyard and build GOT in 3 months, Make it a surprise announcement...
Eh, one could dream. I'm not even a fan of the show, I like seeing good deals made and businesses I support do well, and even if I don't watch the show, I'd go out my way to watch it for HHN so I know a bit of what is going on, and I'm sure the maze would've been amazing.
