What I'm saying though, and I'm not a tank expert, but you know how some lines are known for gun depression, and other lines are known as brawlers, and another line might be known more for sniping...what would the new line be known for? I heard a Dad say just the other day that the end-goal seems to be having a duplicate of every tank in every line. So every line gets a T-71, every line gets an IS-3, every line gets a Hellcat, etc. So what is the purpose of adding a new nationality, other than just being something "new"? Surely someone out there is going to think it's the best change ever. I'm just not sure I get what was "missing" that we need a new line. And I mean it questioningly, I don't know.
Basically, I think WG wants new content to keep the game going. Perhaps they are running low on options for the current nations and need a new nation (or a few).
I'm glad its not just more Chinese copies of Soviet stuff, Czech tanks are certainly more interesting that Chinese TDs or SPGs.
Edit: Also what's up with my username being purple? Stands out too much...
