I did get a response from Obsidian today. I contacted them via messenger on their Facebook Page. I have posted thee cut/paste response I received in my forum post (link below). Hopefully they will make a formal post on this soon.

Hi everyone - I'm making my rounds around the forums to make sure I hit as many people as possible - I wrote a formal announcement here about the state of the rewards and the reason for the lack of communication (we really wanted to have stuff to communicate first), but I'll be personally updating this thread weekly to make sure you guys are all up to date on what's going on in physical rewards land. Whatever the reason, we shouldn't have gone so long without communicating with our backers and we won't do it again.
