In any case, the expression "New Age" is strong of meaning.So if the development took 50 years, there'd still be no way to decide whether it was slow or not? It's kind of sad to see the standard space software that must not be named excuse trotted out to defend Frontier's lack of progress on the updates they said themselves are coming.
Unless of course 2020 vision contains all that was trailed and more. Who knows, because Frontier refuse to let that information slip to their 'vibarant community'.
This expression should not be used lightly.
