As much as I'm a fan of the Shats, I have to agree in the story being told here (as much as we know about it, anyway) there just isn't a realistic way to work 'Old Kirk' into the story. If Team Abrams is adhering to canon, which apparently they are, then they have no choice but to deal with the fact that Kirk is dead. If Generations
hadn't happened, then I'd be all for it.
So no, I'm not holding out hope that this is all to keep a Shat cameo secret. This is Spock's story and I'm cool with that.
