There have been several game changers in the last decade, the RED camera being one. It's price was low enough and quality high enough that they have become somewhat ubiquitous, creating relatively low rental prices and creating a whole new generation of cinematographers that were able to skip the typical slow apprenticeship track (for better or worse). An equally large game changer was the rise of the DSLR, opening the bottom of the market to a look previously unreachable for the price. I love Blackmagic (have the pocket camera myself), but the difference in quality and cost between current DSLRs, the various REDs and the Ursa 4.6 is not great enough to categorize as a game changer. I'll probably pick up the new Ursa myself, but at this point the visual quality of the picture is the least of a filmmakers worry (check out Upstream Colour which was shot on a $1k GH2). Shooting on a cheap DSLR and spending more money on art direction will have a greater impact on the quality of a film than picking up the best camera and lenses.
