Amazon listed two (so far) new exclusive sets on 9/3.   They are:

Star Wars The Force Awakens 3.75-Inch Figure Troop Builder 6-Pack - actually has 7 figures. Captain Phasma is joined by uniquely armored Stormtroopers and Snowtroopers.  The fact that it is not actually a six pack once again robs me of Black Flag jokes.

Star Wars The Black Series 6-Inch Stormtrooper 4-Pack - This is the rumored "evolution" set. Each figure is unique - Stormtrooper has dirty deco, Episode 7 Stormtrooper has a unique pauldron, the Episode III Clone Trooper debuts in this set, and the AOTC yellow Clone Captain is new.

Heck, I ordered both.  You can too.
