Just a minor clarification: Sept 22nd is still an aspirational date more than a solid deadline. We set it as soon as we think it's possible to hardfork, as we don't want to delay the hardfork any more than we have to, and if we set the date later, it's quite difficult to move it earlier (due to coordination requirements with exchanges).

It's still quite possible that the ultimate date will be later due to the requirement to have a functioning hivemind for Hive apps, but we don't expect any changes of importance to hived itself.
