Re: Why are there only two cities in the future? (spoilers)
Which also reminds me of another observation: why does each Trek race now only has a single planet ? Romulus getting destroyed by the Hobus supernova apparently made Nero the last of the Romulan empire, and apparently Vulcan has no colonies until New vulcan. Weird. Isn't one of the points of space travel is spreading around ?
And that's my opinion.
