I believe these would fit the "fast heavy" scheme that the Russian and German trees are both getting. They're unique with their oscillating turrets (French will have these too on the AMXs) and they'd add a lot of variety to the US tree. Much of the components (The hulls) are already in the game, so they'd actually take a minimal amount of work!
How about it, Wargaming?
