I don't think any demand is exotic on it's own, but to get them all together you have to be pretty lucky. You'll need a company that can make a water resistant phone with a card slot, or is willing to give up the water resistant feature. You'll need that company to be able to ship a CDMA version, which is harder when GSM is more common. You'll need that company to not be a *ick company and have drivers for their hardware. You'll need that company to achieve all of that and still be able to get a 820 and keep expected margins.
