Totally agree, I just don't get this.
Should be such a simple fix for them.
I do however love the inclusion of the 1/4" female thread on the actual body. To mount a GoPro 5 on any tripod/attachment you have to encase it in a shell case just to get access to a mount. The Hero 5 is waterproof without a case, but to use it on anything you still have to put it in a case, and that kinda makes no sense.
So "Drops on March 28" means you can pre order for delivery in 8+ weeks on March 28...
