on go pros website it says that the wifi backpack is waterproof. but from the videos I've seen it doesn't look like it will fit in the waterproof case 4 either deco pro 2 or the 3d hero rig, which is my primary concern. Will it work with the 3d hero? How can it if the 3d hero connector is attatched? Isn't that where the WiFi backpack mounts? I mean I'm Definately getting it either way, but I want to remotely control the 3D Hero Dammit!
