you can go to stores and hold them now. i personally don't know, but i have seen pics of a few guys with them....and the videos to boot. i wish i had some $$$
its definatly what i want because i want to step up to a CMOS rather then a CCD if not id just by my friends d80 but since i want some metal i might look into a used d300 iv heard those go for around the same price as a new d90.
