The thing about Shatner; over the years there's been rumors he was a pompous arse on the cast back when they were shooting the original, and left some bad blood for years to come. I know when I saw George Takei at Dragoncon two years ago he seemed to have an issue. Someone made some question or remark regarding Nimoy and Shatner, and he answered the Nimoy part but then he said something more or less who was the other guy and let the topic drop.
Shatner said he was mad over not being invited, Takei countered saying he had been invited. Ultimately it's none of our business but it would have been nicer to see that future world where we got a lot of issues settled rub off a little more on the people who portrayed it. Those guys are all in their sixties+ when are they going to stop acting like little kids? *sigh
I guess my point on the Vette is that it puts 'Trek a little too close to modern day. I mean, Kirk is probably his late thirties by the time he commands the historic five-year mission, and though we don't see much of Earth in the series, there's little to directly connect it to today. Civilization today bears little resemblance to c. 1700, and I'd expect it to be the same case around 2300, which the Trek timeline is rapidly closing in on in Kirk's era.
I guess I'm saying I'll feel uncomfortable if they put it too close in appearance to other established sci-fi that sits within a century or so of the modern day. With 300 years of breathing space, 'Trek always seemed to have a relatively safe psychological distance from us.
Arcologies, yeah, I suspect that's what we're looking at. Makes you wonder what life in one of those would be like...
