K/S slash has such a long and distinguished pedigree - and the new recasting can only enhance such things - that as far as I'm concerned, Trek already has its honorary gay characters.
I'm actually far more concerned how they are going to handle the Spock-Uhura thang...the writers are pretty gutsy to lock themselves into a romance that they cannot easily extricate themselves from, as per Trek tradition, by feeding one party to a hungry space ameoba or simply throwing her under a bus (necessary for stopping the Nazis from taking over the world dontcha know).
And they can't just jettison the relationship without further ado in the next flick, without making both parties seem shallow (not ever an option for Spock and not either for Uhura, especially in her new incarnation). They can "break up" but there will still be an elephant in the room, on the bridge, on away missions, etc.
I think the diverse audience the film is attracting this time around would dwindle appreciably if they left all the romance to people's imaginations, as most moviegoers don't spend time on such imaginings in the same way hardcore fans do. The Spock/Uhura romance has obviously clicked with a segment of the audience and there is no reason to dispense with it. They seemed to know just how much and in what ways to use it in this film, so there is no reason to be concerned if it continues, which I expect it will.
That said, I wouldn't mind at all if they hinted that Chekov, let's say, were gay or bisexual, or if they introduced a new character who happened to be gay.
