If in 8 or 9 months Nikon were to announce the D300 or whatever, (and I'm sure they will

) maybe a 13MP camera for $2000, I'd of course have to be upgrading to that as well. This of course would require a new housing too. So, in the end, I'd be spending about the same amount of money trying to stay "Up to Date" with the latest and greatest.
I think you are confusing Nikon with Canon. I wouldn't be worried that Nikon will obsolete this new camera so soon. Nikon cameras seem to have a much longer shelf life and your comment prompted me to take a look back in time.
While I agree with your decision to get the D2X, I think that others that are trying to make up their minds should not fear that the 200 will have such a short life. Nikon cameras have a longer lifespan than you'd think.
Let's review (with the help of DPreview)
http://www.dpreview.com/reviews/specs/Nikon/Here is a time line of dSLR camera announcements from Nikon
D1 June 1999
D1x Feb 2001
D2x Sept 2004
D100 Feb. 2002
D70 Jan 2004
D50 April 2005
D200 Oct 2005
Of course the actual release dates were later than this and a bit more varied, but you get the idea.
D1x to D2x 3 1/2 years
D100 to D200 3 1/2 years
It can be argued that the D70 replaced the D100 in 2004, but it was a lateral movement, not an upgrade. The D200 is the true replacement for the D100.
Of course past events are no guarantee of future behavior, but it would be fair to speculate that the D2X and the D200 will be the top Nikon cameras for the next few years.
Now, how often you decided to upgrade your UW system is up to you. And if you make a bug jump in class from D70 say to D2X, then you can jump anytime. But if you are a D100 guy (like me) and have enjoyed it for the past three years, the D200 is very attractive and I'd be happy with a good three years out of it.
