I suspect that the new software isn't what's holding up the show. In the course of examining these accidents some other issues have come to light (like the difficulty in using the manual trim wheel is some situations) and the level of trust in Boeing and the FAA are at an all time low. Some regulators may also require sim training, and there are currently not enough sims to accommodate all the operators. This will take longer than anyone initially thought.
