I mentioned this in a separate thread. It seems like a huge risk to release an online game if you don't do this now. A single bad game can take down a studio. Now there's even more risk because a previously successful game may come with a big bill in the future if you have to do refunds or some late architecture change when you instead want to take a product down to save money.
Perhaps they should just write games in a way where they can actually release server code when they it shuts down?
