Actually, no. Let's focus on the bedrock Spock, Kirk, McCoy relationship, instead. We don't need Uhura playing Yoko Ono.
Kirk: Mr. Spock, would you like to join Dr. McCoy and me on a camping trip to Yosemite when we get back to Earth?
McCoy: We'll roast marsh mellons.
Spock: Captain, doctor, the invitation is most gracious, but Nyota and I have plans.
McCoy: Oh?
Spock: Yes. We are going to visit her relatives in the African Republic for a week, then we're going to a spa in India, and finally shopping in Tokyo.
McCoy: Boy, are you whipped.

And yes, I'm in favor of more Spock/Uhura in XII, but I agree with Pauln6 that there'll probably be a love interest for Kirk that takes center stage on the romance front instead. No concrete reason to believe that, but it just seems due.
