Iguess the taping isn’t because of new models, it is because of the olympic regulations.
Here’s a list of all official sponsors, and Nikon is not mentioned:

So, following the olympic sponsoring rules, photographers have to tape their Canon, Nikon and other gear that could be filmed or photographed. They are not allowed to show other trademarks than the sponsor’s.
And I didn’t find something new on the pictures.
