Well my request for presents for the next fews years are now taken.. Nikon have announced the D300 (I've a D100). See the initial summary at dppreview
I love the D100 - wonderful build quality and I've really got some good use from it. The D300 has some great advances over the D200. Noteably to me are 100% viewfinder, 12MP, auto focus that is way superior that the D100. UDMA CF cards, and HDMI video out could be useful.
Plus it has built in sensor cleaning... yes excellent.
Having just got some new lens and filters; no way will I be able to get a D300.. so perhaps Christmas 2009?
