My B-I-L bought the D90 as his first DSLR coming from the F3. He was sufficiently frustrated by the smaller viewfinder and fiddly menus that he steeped up to the D300 almost immediately. And while the D7000 has a 100% viewfinder and a host of great features I think that daswann's analogy is correct in that the D7000 and the D90 will be analogous to their counterparts the D300 and D400. I disagree that there won't be much difference as there are clear and substantial differences between the D90 and D300 and history has proven that those differences were substantial enough to warrant many well informed, objective, thoughtful photographers to choose the D300 over the D400. I have no bought that the D400 will be positioned likewise.
