They'll probably keep it alive for awhile. Maybe I am biased. I did research on AZ a few years ago before ELN/WYE released ph2 data. I kind of followed along the line of one researcher (I forgot her name) hypothesis that BA is side effect of AZ, thus removing BA wouldn't improve AZ at all. I haven't followed AZ research that much since then. I started to do some reading lately, it seems to me not much has changed.
