Although I do like BA, you would be able to get to most destination that BA serves with another OneWorld Partner (Iberia/Finnair) and not have to lose miles! The exception may be Africa. BA services alot of the cities I fly to in Africa and this is where I may be hurt! However, I have not done complete research yet (pending actual notification instead of rumors) and will find a way to get to my destination and earn my AA miles, as always!
