I can't help but feel that the rework did not work, otherwise they would have updated us by now, and they are just waiting to have a firm date on when the new batch will be ready. I have also felt like the the rework is a bit of a useless exercise overall anyway (except for research purposes), as the ultimate goal is to mass manufacture these things without any hiccups, so really we would be waiting for the new batch to perform 100% to spec before demo's would go ahead anyway. I really had hoped to get some news about the completion date for the new batch.
