This take from Gruber “App Store: The Schiller Cut” has a sour taste following the WWDC keynote and Platforms state of the union. Did Apple announce something this week to appease developers relations? Nope. Will they announce something in the coming weeks in regard to App Store commissions? Who knows. If they do, they will do it in a position of weakness:

If someday down the road we will be changing 70/30, then I think the question moves from “if” to “when” and “how”. I’m not suggesting we do anything differently today, only that whenever we make a change we do it from a position of strength rather than weakness. That we use any such change to our advantage if possible. And thinking about this long in advance can only help to look at an eventual change as an opportunity (with developers, press, customers, etc). — Phil Schiller in 2011

They missed the opportunity this year. Apple is in a weak position and I don’t see how this could change anytime soon.
