...and Nikon has a new 'killer' model which was announced recently, the D700 with full frame sensor to compliment the excellent D300.
From what I hear and see, both leave Canon lagging behind.
Canon has had it too good in the last few years but now they face stiff opposition from Nikon, which is a good thing.
It will be interesting to see if they can fight back with better models.
One thing to keep in mind though is that camera bodies will come and go, but I believe a good quality lens system is what counts most.
A good selection of high quality lenses will last you a lifetime.
