Any data about the price?
Nikon Switzerland are quoting 1398 SFR as the "suggested" price. In comparison the "old" 105 macro is 1628 SFR.
These prices include 7.6% sales tax so 1398 equate to about 990 USD (without tax). However Swiss prices are horribly inflated when compared to BH Photovideo.
The markup is becoming less over time but 15-20% is still normal.
