My theory is that the line between SPGs and tanks begins to blur, resulting in relatively heavily armoured vehicles that are capable of armour-penetrating direct fire when necessary but spend the majority of their time flinging ordnance from over the horizon to avoid drones and infantry antitank.

Meanwhile IFVs universally get equipped with airburst 30 or 35mm rounds and systems to effectively use them in an c-uav role.
