For what it’s worth, JTB only started actually processing the applications on the 15th.

This is based on comments made by a government official in a TV news programme on Sunday this week, and officially was nothing more than that official’s opinion. However, the rumours (“reports from anonymous officials”) are saying that something is likely to be announced by the end of this week, and that it will be the removal of the need to apply for a visa starting from October. These “reports” have been accurate in the past so I’m hopeful.
