It will surely arrive sooner or later. It's always hard to wait, but as OS4 is not out yet, slight changes in AmigaONE delivery deadlines is not a big deal methinks.
Use tactics like KDH, add two weeks to each date when it arrives, or don't believe the overly optimistic user opinion based deadlines, and be a little more sceptic towards the less overly, yet optimistic official deadlines.
There's little chance to the OS4 or AmigaONE project to be cancelled, so there is nothing to worry.
