B & H will auto notify, but don't have orders open and likely won't until official pricing happens at the end of Jan.
A small window opened with Amazon a while back. I have an order that still shows as pending for the body, but didn't get in on the lenses. They posted and closed the lenses before the body was posted.
Interestingly Amazon's price on Jan 8th when their widow opened briefly was $1699.95, which is the whisper price at the moment for the body (a little high I think).
I'll keep my order pending reviews of the body. I fear if the reviews are good I won't be able to get a body ordered for delivery anytime soon if I drop the one I have.
I also fear I'll have a body with no lenses since I was not able to order the lenses.
Maybe I'll find someone who ordered the lenses but didn't get a body and we can arrange a "shared custody" agreement.
