I think a split is inevitable at some point. I've never yet seen the company fail to achieve what it wanted eventually. Usually BALPA gives up something in order to prevent it happening, and then it just happens later on anyway. It is for this reason that I was strongly against the BMI concessions - indeed it was a significant part of why I left the union.
I wonder if they'll change command courses in order to improve the success rate? I know perfectly capable pilots who have been utterly broken by the command course system. It is no wonder that a lot of people would rather just not bother putting themselves through it for the sake of a short haul command.
