Looks like the new Nikon D90 will be announced this week. The D90 will replace the almost 2 years old D80.
Not that it means much for us wedding photographers but we can expect it to be as good as the D80 and of course better.
It will probably sport the same sensor as the D300 in a smaller, more advanced-amateur package rather than the semi-pro D300. That will place the D90 between the already famous D300 and the new amateur oriented D60. Check here for more updates.
