Well in all honesty the D2x is most of that anyway.
HDMI output - Not sure I know anyone that will ever use that, it's more a gimmick. The 11fps is only in crop mode, its 9fps in normal 12MP mode ( although fast enough for me )
Twin card slots will be needed as I'll have to shoot raw+jpg until Aperture can decode the new raw format.
But it's the better ISO performance I'm after, especially as I'm going into wedding photography too.
I'm number 8 on the list at the
shop I've got my order in with, so I hope they get more than 8 on the first shipment ( fingers crossed )
