So someone grabbed this screenshot at some point during PAX, and based on previous evidence, seems likely it could be the 4th race:
Sorta confirmed in this video as well "nameless race, that... you get a quest from right here"
(Skip to 8:25, I coulnd't link the exact spot for some reason)
Hilariously, the quest seems to be you riding an explosive-packed rhino around in order to find poachers to explode, all while avoiding other 'horny' rhinos
