Not sure if it's been said. But my understanding is changes like this are phased in - ie won't change it all in July 2015. Also I thought some/most of these changes aren't due to 1 July 2016. It's done this way so people can plan for new system.
Found article that changes are proposed for 2017. So if anyone stressing over current situation, looks like you will still be under current system not new.
