Yeah, but Link has no personality(outside of certain games like WindWaker).
It's not the gender that makes a character, its the quality of writing, and Link just isn't that interesting. It would just be another Zelda game if all they did was change the character's gender. Unless Nintendo are sufficiently married to the idea and change up the game significantly to reflect a female perspective, it won't make much difference.
Appropos to the writing being a crucial factor, Geralt of Rivia may be a "generic white dude" to some people, but he has a lot of nuance that most AAA games' protagonists don't. He is respectful of nature, aloof, but understanding. Charismatic but also stoic. Resourceful and insignificant. Changing his gender would change everything in the story. Literally, everything, and it would be more siginificant than a gender-swapped link because the games would have an entirely different story, and an entirely different feel to them considering its another Game of Thrones-esque, high fantasy, dark medieval RPG.
Also, CDProjekt are Polish devs, not like the US-dominant game devs who make the majority of "burly white dude" game's protagonists. Cultural variation does make a difference, and since they're one of the few prominent Eastern European devs out there, I don't think they deserve as much crap as say Activision does for their constant lack of well-written female protagonists.
