I'm not exactly the biggest fan of DBSK but I do like them a lot and it makes me sad to see this PV cuz I think, and I know that we all think it and we don't want to, but I think they are nearing the end of the group
Its awful and sad but I think they've just reached a point where they've found their differences. Jaejoong, Yoochun and Junsu caused an obvious rift with the lawsuit (which is a shame because they are only asking for what they are entitled) and if Changmin and Yunho had of backed them up then I think it would have been solved long ago and they would have been fine. But now I think that SM are pushing wedges between them (ok there is no actual proof of this but knowing SM I wouldn't be surprised if they were blackmailing Yunho and Changmin to keep quiet about things).
I think that although the official line is that DBSK/THSK is still a group economically I think that they disbanded long ago emotionally
