If video style production with a long zoom is important, I would go for a 2/3" camera instead, like the HPX500 or the new Sony. The sensor size advantage in DOF will be lost if the zoom lens has an aperture smaller than f2.8, and that aperture will never appear in a 10x or 16x zoom at 4/3. A 3x f2.8 zoom at $2,000 is easy, those probably already exist, but things get extremely expensive and hard to design after that point.
Except that the cheapest 2/3" camera (HPX500) is going to cost 3-4 times as much once set up, plus P2 media. I totally get what you're saying, but if you're shooting a wedding a full size P2 camera is going to be a bit large and obtrusive, and nice primes will not always be workable. And honestly, looking at GH1+kit lens footage on Vimeo, I'm more than happy to "settle" for the longer depth of field, because it still looks a lot nicer than what I get now. If I do end up buying this thing, the first thing I'm getting to go along with it is a nice set of primes. But for the market that this will most likely attract and be used for, primes simply aren't always feasible to use.
