But right now they are the only answer to the question, "What high quality kit can I hike/ski/bike/kayak/jet ski/snowmobile all day with, capture clean, in focus action shots, and is smaller than a DSLR?"
As long as they are the only game in town, they can add a price premium. The fundamental question is...are there enough people asking that question?
If the image quality is a big step forward (not that it was bad with the V1), I'd strongly consider the V3 kit and the 70-300 zoom.
