Surely, they have sought out a sensor partner that is more reliable and they probably also have a good grip on what the interest in the product might be?
I keep seeing people blame the BMCC delays on the sensor supplier but from July to September I recall (which means at my advanced age, I could recall wrong) the delay being explained as a w8 on beta testers. IIRC, there were other excuses given as well. I didn't save the paper trail...anyone remember?
