I understand you personally want to see it, but the tank is already in game in some form and asking every major update is not going to change that unfortunately.
There are many vehicles, variants or national operators that could have been added of many vehicles across the game. They are not all introduced at once.
As we have said, its possible it may be introduced to the British tree at some point. But right now, its not within plans for this major or relevant here.
You are more than free to discuss any rumours in that topic. That's entirely correct. We are naturally following all the discussions and topics regarding the dev server.
We however do not officially comment on things not yet announced. Being in the files is not an offical announcement in that regard.
