We have plans to include new maps that have a focus on tanks. That being said, note that FH2 is not a game like War Thunder or World of Tanks. Tanks are only one part in the combined arms concept and infantry will always be the majority of players, simply because that is how it looked in real life. Even a "tank battle" like Prokhorovka had way more infantrymen than tanks.
Increasing tank numbers to a big degree would devalue the tanks, since they would become disposable. Also, if infantry would be gone or heavily diminished, the complexity of tank gameplay would also decrease, since whole elements like HE shells, co axial machinegun, passenger seats etc would basically be made worthless. All that would be left is tank vs tank combat with the occasional plane.
Now I understand that if you enjoy tank combat a lot you might be annoyed by not having a tank always available, but that is the perspective of a player, not a developer. I am sure many players would prefer it if sniper rifles were always available to them for example, but (not even mentioning balance) their scarcity is exactly what makes them special and "cool".
Often it is the limitations that make something interesting.
