The next Nikon press conference is scheduled for…

… July 30th and August 4th. Double whammy? Maybe D300s on July 30 and D4000 on August 4th (300->3, 4000->4). Stay tuned – I am sure I will be getting more confirmations from around the world in the next few days.

This news comes from Nikon Nordic and the event will be held in Stockholm, Sweden.
