It’s also likely that the network will continue to be coy about any sort of definitive answer until Game of Thrones concludes, presumably in 2018.
One potential source for inspiration is Martin’s own prequel novella series Tales of Dunk and Egg, set approximately 90 years before the events in Game of Thrones.
Still, there are certainly some fans who won’t be initially on board with the idea of oversaturating the Game of Thrones name with spinoffs for fear of diminished returns in terms of quality.
While certainly a valid concern, if Game of Thrones does indeed conclude on a high note, it could prove to buy HBO even more credibility when it comes future ideas they may have with the property.
