I mean the D7000 has a new sensor, new processing engine and new autofocus chip. I mean, why introduce new technology if it isn't better than previoously technology (speaking generally, of course!!)?
It obvious that the goalposts have shofted with this new technology and will defintiely mean that the cameras following the D7000 will also be significantly better than their corresponding predecessors.
I am quite excited to see what will be coming next!
