There are only two races officially revealed, the Jin and Gon. However, it is suggested that a third class, possibly a fox-like character who appeared in the trailer video, will be implemented in the future.
Jin - A race that is similar to humans appearance-wise, and specialize in sword-based combat.
Gon - Physically stronger and larger than humans, Gon specialize in hand-to-hand combat.
Unnamed Fox Like Race - Small and petite than most characters with fox like tails and ears, they seem to specialize in speed based combat,however there is speculation that they can transform into a more beast like fox form as seen in the trailer.
The trailer video revealed that players will be able to combo skills, and that players will be able to jump and dash while in mid-air, through a system called QingGong. According to an interview with the Development Director, players will also be able to make wine and pottery.
