Well,not actually GOT,but the prequel. It is titled "House of the Dragon",and is the beginning of it all.
Trailers look to be very interesting,and I have no doubt that with the experience the crew now has from GOT,that it's going to be spectacular.
Right now it SEEMS like it is only going to appear on the Spectrum channel,but I suspect that will change before airing. I would be shocked if HBO doesn't get a piece of THAT pie.
