Will all classes hold spear on one hand when unsheathing it, despite it being 2 handed weapon?

Holding Spear on one hand makes perfect sense for especially classes that plan to use Spear on range, or in case of wielding it with another weapon, but for two-handed melee fighters I'm hoping we will see another stance, much like Staff weapons have for melee and caster stances, where spear is held differently with both hands on the spear as you enter the combat.
