I also don't think they will add a 125k level because if they do it will be in conflict with what oneworld offers; 75k will have all the benefits 50k have, lounge access, etc. but will earn some additional perks within the AA program.
Losing OW Sapphire and/or 100% RDM bonuses would be significant devaluations in the MM program but I agree that one of them will probably go. It's hard to say which would be the lesser of two evils - losing OW Sapphire would probably be a bigger blow to international travelers while not such a big deal to those who travel on mainly domestic itineraries (although it would still be a blow).
