Firaxis, are units going to be built like in Colonization?

I hope that units are built like in Colonization where soldiers were equipped with weapons. It's very frustrating have to waste turns rebuilding my armies after new units become available. Basically, phalanx units can become musketeers just by throwing away their spear/pike things and picking up muskets. Then a possible building could be "Weapons Workshop" and upon the invention of Gunpowder, Bolt-Action Rifle, etc, it would cost a certain amount of gold to upgrade your Weapons Workshops to make the new weapons.

I don't think they will be.

However their probably should be some way to spend only a small amount of money to upgrade units like in SMAC.
