I would hold off for just a little while (or really make sure your dealer knows what they are sending). There are two versions of this thing out there already. One has a the rear connection to the GoPro, but that version is (for some at least) producing interference/noise in the AV output that you would feed into an iOSD/video tx. Very quickly (as in just a few weeks after release) DJI released a second version that connects to the GoPro via USB for acquiring AV and for charging. This second version, apparently, does not have the degraded AV out issue. There likely are still first versions in the supply chain. The whole other issue -- getting one not made exclusively for a Phantom -- is unclear from what I can find out, but I haven't seen anyone out there posting or commenting on using a non-phantom version yet.
