Nikon D300 Discontinued….D400???

The fantastic Nikon D300 has been discontinued (so has the D60) and rumors are now starting to come from more reliable sources that the D400 is on the way. The rumored spec on the D400 (if that's what it would be called) is:

HD movie funtion with stereo sound. * 16-18mp sensor (DX format). * Articulated screen (like the D5000). * Better ISO performance (at least as good as the D90).
