Lifted from Nikons tech site

Yes. Nikon plans to offer a firmware update for the D200, however it will only adopt the D2Xs "Image authentication" option in the setup menu. Support for the optional Wireless Transmitter WT-3 will also be included in the firmware update.

Quite fancy a WT-3...

You and me both :D Although I don't knwo how practial it would be at gigs :norty:

Although I thought the 200 could already accept the transmitter.
