I think it is fairly easy to calculate what your costs will be based purely on the latency of your requests and the number of requests you are getting. The new scheduler will anyway not affect this and based on scheduler knobs + front end instance resources, you can somewhat predict the no.of instances you might require.
My gripe is, the new pricing brings latency into focus, while the developers have nothing but their app code to optimize it. The responsibility for latency is both on the application as well as underlying infrastructure.
