Delays in the production of new automotive designs is not all that uncommon. It's just that this particular car is highly anticipated and very public. I've had the opportunity to speak with many of the engineers and designers working on the NSX and from Ted Klaus on down, they all regret that Honda announced the car so early as it has put a lot more pressure and scrutiny on the team.
As for the factory, G.Irish is correct. There is a ton of training and practice that happens before formal production is started. What you are seeing in Monterey and driving on the test tour are some of their practice runs. That factory was fully staffed over a year ago.
And the article....my dad always says "believe some of what you read, half of what you see and none of what you hear." The GTR was not the main bench mark for the NSX. It was the F458 (and recently 488) and the McLaren MP12. With so little information coming out of Honda, the media is making a lot of assumptions and some just aren't accurate.
