First and foremost is the revamp to the game's Soviet tech tree, which sees heavy tanks split into two separate branches. The 7.3 update also brings a new South Coast battle arena to World of Tanks as well as Dragon's Ridge, the first of the game's maps to be set in Asia.
"We've got loads of exciting new content to share with our players," said Victor Kislyi, CEO of Wargaming.net. "The new machines should give players a taste for heavy vehicles, and with the help of the upcoming battle arenas, the game will get a fresh look from both a visual and tactical point of view." You can get a visual preview of 7.3 via the video after the cut.
