well.....miki quit Momusu so that she could concentrate on her solo career so I don't think there's any reason to doubt her solo comeback. Although that said, I still hope Ayaya excels in her solo career more so if GAM had to be disbanded, they'll definitely be together in sum sort of shuffle or what not.
Besides, those two always hang out together, even during short breaks (kinda like W), so I don't think they'll miss each othre so much.
So, my final say......GAM being disbanded is neither a good or bad thing. I just hope it leads to a better future for both. Besides, all of GAM singles don't really project Aya's singing, they seem to favour Miki's voice more. Its a shame I tell you
BTW, me huge Ayaya fan....
