I think it is very hard to judge that at this point. There are a number of open questions about the '05 NSX. Will it be the new version? If so, how much will it cost and how much power will it have? It if comes reasonably priced with good power, a lot of people will look to upgrade and the price may drop. If it comes out with a lot of power and a price to match (or just a ridiculous high price tag), an '02 could increase in value (since people can't afford the new one and will there for pay more for the old one). While it looks like the overall response to the HSC is positive, it remains to be seen if people will really like the design. I for one (realizing I'm in the minority), do not like and would not plan to upgrade to it.
