He does resemble Ganondorf a bit. He has rounded ears which is something Ganondorf had in OOT and manly sideburns like OOT Ganondorf. He also is very muscular like Ganondorf. The fire for hair is also the colour of Ganondorf hair. So he could be based on Ganon or have some design ideas. I don't know if he will reside in Ganondorf though, there are so many possibilities of how he could relate to Ganondorf in the future, but then again he could be completely unrelated. The reason I think he will be related to Ganon though is the fact that this game will explain why Ganondorf showed up. I do not believe those 4 chan rumours saying Ganondorf showed up because of zelda's wish. I think it will be because of some ancient evil, reincarnating. I support the theory that there is more than one ganondorf. Aounuma said there is one timeline, so FSA is canon to the timeline that SS and OOT are in. This would be impossible unless there are more than one Ganondorf's. One obtained the triforce of power and was born king of the Gerudo's the other obtained the trident and was not a Gerudo king. That means there is at least 2 Ganondorfs'.
