There are plenty of "Waterproof" drones out there. The problem is that you guys want the DJI video system to go with them. You're not going to get that for $1500 anytime soon. Why? Because there's TOO MUCH MONEY TO BE MADE from people willing to pay a helluva lot more for them when they happen. It will be a long time before this is a "$1500 product," gentlemen.
Lily's a nice little machine (will be), but she's not even in the same class as a Phantom, Yuneec, or a Blade camera equipped multi. She's not designed to be. She's an action camera that flies for the action camera folks. TOTALLY different marketing segment for the most part. There's some overlap but not a lot.
People who shoot video with an iPhone and people that shoot with a DSLR like I do are totally different markets. The low hanging fruit is where the money is right now. Why? There's more of them to begin with and secondarily, they ain't near as picky as we are. And, they have money to spend.
