From an interview at the Tokyo Game Show:
Quick summary:
-ARP Takao event to start in October (ASIA server for now probably), and lasts until December
-The mission to obtain her will not be easy, but will be set at a level that most people will be able to finish
-This is probably last of ARP events for now
-Haifuri event will start in first half of 2017
-TGS goers will get special Yokosuka Girls’ Marine High School flag
-Spotting xp bonus will come in next update in late September or early October (9.12?)
-British cruisers will appear in mid October
-British cruisers will be something between DD and CL. Developers are still struggling with their balancing
-IJN DD branching splitting will come in mid October, but after British cruisers
-One of the reasons for IJN DD branching splitting is to increase their popularity which has dropped after the introduction of Soviet DD
-Clans will come soon
