I was reading the feedback from some of the links in the Delta.com/Blog, and I noticed this from the Forrester Blog...

The Diamond tier will recognize and reward Delta's "road warrior-est" of road warriors -- and, again in theory, keep some of members flying Delta and its SkyTeam partners for an extra 50,000 miles/year. Delta's tossing in a bunch of benefits, including complimentary access to Delta's network of SkyClub airport lounges. It also makes public a "whispered" program nicknamed "white envelope." Until now, Delat's fourth tier was not publicly communicated. Members only knew they qualified when they received their special "super elite" card in (allegedly) a white envelope. The Diamond-level program is potentially worth millions of incremental revenue dollars for Delta, so Wall Street should cheer this news as well.

Assuming that this is correct, since I think Delta would have briefed Forrester on the program before they published this, I don't recall it being discussed anywhere that Diamond = Executive Partner.

Interesting...
