Is it reasonable to expect Paas service providers like Heroku and Engineyard also to cut their prices, or is it asking for too much? On one end, it seems logical to me because their services are built on top of AWS for the most part, on the other, I am not sure if this might happen since their selling point is not the Infrastructure underneath, but rather the convenience and ease of getting something up and running. I guess we'll just have to wait and watch.
The linked page is only describing a price change in S3, not all AWS services across the board (most of what you're doing with Heroku would be incurring EC2 costs).
