WG participates in Tankfest under the title of "World of Tanks". It is a huge event dedicated to historic armored vehicles, which is held on 25th-26th of June. Here is a trailer to give you and overall idea:
Apparently, they've prepared a special Garage, which will appear somewhere in these dates. The screenshots below shows that the in-game screen resembles the main entrance of the venue in almost every detail.
Pictures of another garage leaked. Like the name suggests, it is a beach. There is no information yet when and why WG will introduce this garage. Though, you can use a mod [the link will appear here soon] to make your test server WoT client use this garage right now.
