There is a news post on things coming up for 2017 in WoWS!
http://worldofwarships.com/en/news/common/whatsinthebox/The main things coming seem to be:
-German DDs
-Soviet DD changes
-Clans (finally!)
-Commander skill revamp
-Historic Commanders
- PvE modes similar to the Halloween challenge
-Depot
Honestly, this all sounds pretty good to me. I'm excited to see what they do with the PvE modes, as I thought the Halloween mode was a ton of fun. Historic commanders also sound intriguing. And of course, I'm super excited that we can now have an official MBS clan in side the game!
