In [url=http://www.bungie.net/en/Forum/Post/66559411/0/0]this[/url] thread regarding proximity chat, DeeJ said that he would pass along the feedback to the people who should see it. Now, the game has gone gold. So why do we still not know if they implemented it? Unless it is being crammed in there with a Day 1 patch, the people at Bungie would know if it is in there. Why not just tell us? Stop saying that beards were the #1 most requested thing from the beta. Voice chat was. Address it.
Honestly I think its going to be patched in much further down the line. Proximity chat is something they only saw on the forums a few months ago. It might even have to wait till Destiny 2 comes out.
