I think the spin off shows are going to fade into obscurity.
Let's face it, Captain Kirk is THE icon.
Like James Bond.
Like Batman.
Like Superman.
I think the future of Trek is going to be constant reinvention.
I don't like the new Batmobile. But I love The Dark Knight.
Equally I don't like the new bridge (so far.) But will it stop me loving this reinvention? Hell no, so long as the story is good and the actors deliver.
Again playing devil's advocate, I think there's one minor flaw in this analogy. These people, Batman, Bond, Superman, were fictional literary characters BEFORE we ever saw them on the big screen or TV.
Star Trek TOS and the characters in Star Trek have been played by only one set of actors from the beginning, and the stories have (more or less) followed well, one canon if you will.
I'm not saying it can't survive a reinvention, or reboot or whatever you want to call it. I'm not saying this movie won't be good in it's own right. But I'm just saying this case is a little different than these other examples and I'm not sure I'd hold them up as a comparison. For better or worse, Shatner, Nimoy, et al, ARE Star Trek (at least up until this point).
