Possible, but Panasonic's global shutter appears destined for their highest end video cameras the next few years. Sony, Canon, and others are also working on global shutters. Global shutters have existed for years, but have seen limited use because the downsides of heat and low dynamic range tend to outweigh the upsides.The new panasonic organic sensor and Global shutter could be the start of a sensor arms race, so sensor prices could just as easily skyrocket.
Also consider that a well designed global shutter would entirely remove the costs of mechanical shutter, all while increasing reliability. For video users, high dynamic range global would be a gift. But for still shooters, mechanical shutters are well proven and do a great job. If the global shutter sensors were priced too highly, then camera companies would continue to use mechanical shutters. The Sony A9 has an extremely fast readout electronic shutter. It's not global, but for many still uses is good enough.
