Well, there is more details on the Panerai PAM587 on the Panerai website. Here are the links:
The Panerai PAM00587 Radiomir 1940 3 Days Marina MilitareAcciaio.
Best news? Screws are back...
There are also other Special Edition pieces to be launched in Watches&Wonder 2014 but the other interesting model or set is the Panerai PAM00785.
The PAM00785 is a box set of two watches, a Luminor Black Seal 8 Days Acciaio DLC 44mm and a Luminor Daylight 8 Days Acciaio 44mm. This is a Limited Edition box set of 500 pieces. Both watches will feature Panerai in-house P.5000 8 Days movement. Both watches are inspired by Panerai PreV watches from 1993 to 1997. I understand the set will retail around USD 20,000.

Will update once I have more information.
