According to a local sales staff of a reputable business I've talked to, D90 is still being produced and sold in the asian markets... Reason being the price gap is too big a jump from D90 to D7000. So in effect, D7000 ISN'T really a replacement for D90. When D800/E comes, D700 will still be produced and sold (will we see a price drop of not, it's hard to say). Frankly, if you do not look at the age, one can consider both D700 and D800/E a class of their own. Technically, D7000 can't replace D300s because some features and ergonomics are not really "there" at the pro level yet, so you can't really say it's the king of DX. While some specs seems better than D300s from D7K's perspective, but c'mon... 6 FPS versus 8 FPS (with grip), which one do you think have a better chance of capturing critical moments within a split instance? Same thing for D700 and D800... max 4 FPS (at RAW) versus 8 FPS (with grip)?? So I'd say D700 will continue its run until a TRUE replacement appears... Same thing for D300s... There WILL be a replacement model for the king of DX, whether it's called D400 or not I don't really know. Who knows? D310?
