No offense to gay people, but Bond isn't gay.
The man fucked women through 21 movies and several novels and short stories... the character definitely isn't gay. I don't think I would approve of a character change in that direction. The only way I could see it happening is for queen and country or something to that effect.
Seriously, I'm not a homophobe. I support gay marriage, and I have a lot of gay friends. One of my best friends is gay. It just isn't in Bond's character to be gay IMO.
