The Kirk/Marcus relationship will obviously be a big thing in the next film, seeing as how she got transfered and he was eye-banging her throughout STID. I'm wondering if they're going to have the birth of David.
I'd like to see some more done with the Vulcans. They've lost their homeworld, the population has been decimiated, but aside from seeing Prime-Spock nothing more was said about how they were coping and what they were up to on their new planet.
Also I want TOS and Movie-era aliens in the background mix of crewmembers.
And of course no lenseflares.
