Black Desert developed by the Korean game company Pearl Abyss is currently in second closed beta in Korea. The Russian and Japanese versions have also been confirmed and this game will be published by GameOn in Japan. We still have no updates on the western publisher of this game.
The Japanese publisher GameOn just released a debut Black Desert trailer today. You might have already watched most of the clips in the trailer except for the impressive mounted combat part started from 1:37 and you are also able to get a sneak peek at the elephant used in Castle Siege and Tamer and Wizard combat after 3:00. Check it out below.

Edit: This is the first MMO that I love their mounts.
