First of all, there is no D3X or whatever. Spreading rumors about the next camera before the current one is even released is a plague of these forums - people who spend more time talking about equipment than shooting with it. 90% of the rumor info posted on photography forums turns out to be incorrect. Obviously, there will be more cameras from Nikon. But no one posting here really knows the details because the people who do know can't tell you.
Today's cameras are computers and as we all know, computer life cycles and time-to-market cycles are much shorter than traditional SLR cycles in which models remained current for many years. There's ALWAYS going to be something else coming out next that is presumably better (although frequently just has more marketable functions thrown in that no one uses anyway.) Ten years from now, we'll probably be shooting with 100MP cameras, the noise issues with small photosites will be solved and computers will be fast enough to handle the large image sizes so that it doesn't negatively affect workflow. It all sounds great, but want to wait ten years?
If you always wait for the next thing, you'll never buy anything (which actually is fine if you're satisfied with the performance of your current equipment.)
Also, I don't know how others feel about this, but I always find it a bit grating when someone writes, "Convince me not to..." or the like. Maybe I'm nuts, but I always find that to be a passive-aggressive stance. It's not anyone's "job" to convince anyone of anything. It's one thing to say, "help me understand the pros/cons of a 12MP vs 24MP camera" and quite another to imply, "I dare you to stop me from buying this camera." Read the forums, research the facts and see how it all fits in with your needs and shooting style. Then make your own decisions.
