They'd probably make more money that way. Which I think is why they're moving towards it.

Even if it was the same money, people buy it when it comes out so they spend money making it for a year, and get all the profit at once.

Skins sell constantly, and keeps them profitable everyday. With a hyper focus on "quarterly earnings" this keeps stock up all year even if total profit on the year is the same. They want that sustained profit.
