MindShiftGear Rotation 180 appears to be shipping
This looks like an excellent backpack/camera transport system. I'm tempted to buy online. However, I would prefer to see in person as I have concerns about how well the rotating waist pack can support the weight of the upper backpack. None of the usual online dealers seem to have these yet.
There are two versions, one basic, and the other "professional deluxe" with several useful accessories included for a small overall discount.
This product, or something similar, is on the want list for sure!
