Wargaming.net just published an article that explains the main features coming in World of Tanks v.7.0 in November. Here's the rundown:

• New divisions of tank company battles will be introduced for players with lower tier vehicles. The divisions will be Junior (tier 8 maximum), Medium (tier 6 maximum) and Champion (tier 4 maximum).
• At the beginning of a battle, the team won't see the number and names of enemy vehicles. The enemy tanks will appear only when detected by teammates.
• Any tank destroyed on the Global Map will be detained from Ultimate Conquest battles for a certain period of time, depending on the tank type and tier.

In addition to these main features, Wargaming.net has outlined even more plans for v.7.0, including the introduction of the new Marsh and Fjords maps, camo and horns customization options, a complaint system and more.
