Cameras are to indie film makers as laptops are to web startups: important to have but not their biggest concern. Pro cameras can always be borrowed or rented if need be. The bigger concerns for an indie film are paying for a lighting crew, a sound crew, line production, then months of editing and post production, and then trying to get anyone at all to distribute the finished product. Nice camera? Yes. Game changing? No.
I think for a lot of indie films it's a bunch of guys in a profit sharing scheme living on ramen noodles. Back when I was applying to college I looked into film school, the 35mm film costed $600/minute, and since they're photo films you can't overwrite them. If you screw up you throw them away. So in effect the medium is the weakest link for a lot of indie people, especially ones on the low end of the spectrum.
