The ruling has no comment on Apple contractually limiting devs to charging the same price, so it is not at all clear that the price will be lower. These kinds of contracts are quite common in many retail sectors, so it wouldn't be unusual. Apple App store is still the only way to get on the platform. Devs will get a bigger cut.
