Wargaming RU uses the Twitter to sometimes quickly mention upcoming features. Here's what they wrote recently:
- another "tank marathon" ("grind a gazillion XP to get IS-6" and such) is coming (to RU server anyway and no, these events are not always shared)
- new chat system will come by the end of summer
- the issue where you get the same map many times in a row is going to be fixed soon
The last one is doubtful and most likely a PR stunt, as Storm yesterday confirmed this issue will not be fixed anytime soon. Nevertheless, we will be waiting.
