For an art of harmony, these types of splits are disturbing. Aikido was evolutionary from what I am able to gather from O'sensei's history-i.e., his aikido changed with time.
The aikikai has a responsibility to maintain a certain set of standards to certify dan ranks-otherwise these minimum standards would be inconsistent and vary dramatically for everyone. So why do we have to have another separate organization because they want to practice a style developed when O'sensei was at Iwama? I think the statement about ego was pretty much on target.
I know it is not going to happen but I think people should evolve back to the aikikai and restore harmony.
My two cents.
