I think it's fairly safe to say that if instance hours represents a significant part of your expense (as opposed to datastore ops or storage), Java will save you some bucks. It's hard to predict how much - it will depend heavily on your app. The key differentiator is that Java's serialization and garbage collection are significantly faster than Python's, and GAE service calls require a lot of both. No, I haven't run apples-to-apples benchmarks... but issues like http://code.google.com/p/appengine-ndb-experiment/issues/detail?id=118 give me cause for concern. FWIW, I develop GAE apps in both Python and Java, and like both environments for different kinds of projects.
