LanOC has published a review of the Logitech G604 for those of you interested.
Funny enough the G602 was replaced with the G603 but it dropped the extra side buttons and went with a different shape so it was a little bit of a surprise to see Logitech switch back to the features of the G602 when I had a call with them about the new G604. It gains the Hero 16K sensor of course and drops some weight.
