Actually it's soft confirmed than we will choose our emblem. (we receive an exclusive emblem with OpenDev participation, representing G2G community). And they teased in the AMA or QnA, a "really cool" lobby, where you choose your things, with no any specific informations. Seems the easy way to identify each player with his player name, his emblem and his color. And it's cool to have some culture related symbols, and no only abstract ones.
