The movies will be more ensemble than a 60's tv show was ever going to be, yes. But the core story will still be Kirk and Spock. Despite being able to do more of an ensemble story JJ has really only used the rest of them as decoration. This is one element of why so many original TOS fans (including myself) have found JJ's Trek such a satisfying reboot of Star Trek. It feels like TOS because it is still primarily about the relationship that TOS built so much around.
I'll agree with this for STID. The '09 movie at least made successful attempts at inclusion, and not just in terms of face time, but actually doing something important. Each character got something, and that was nice. They felt more like a "family" at the end of that film that during the entirety of STID to me, so I can definitely understand why TOS fans are happy.
