I guess I'm rather slow in catching up with the news, busy days and all.
I'm feeling rather alarmed and cautious about this. I'm not all that much opposed against change itself (to be frank, I'm mostly attached with four out of the seven girls, and I'm feeling pretty safe that they would never be replaced) and I would welcome any new member additions. Though I don't really see the point of adding more members at this point in time (6-7 is probably ideal for a group), I can see ~9 members working as well (see SNSD).
What seems rather unreal is the 'threat' of replacing members. Which is essentially, firing someone, and I can't see any fan particularly impressed with this. Or the remaining group members themselves, for that matter. While, again, to be frank, I could personally tolerate some members replaced, I find it hard to accept this as a well thought out move.
I assume the only financial reason to do such a replacement would be if the management would be trying to enlarge its fanbase using 'new' personnalities that would appeal to an audience that T-ara currently does not. Then they'd accept the damages of losing an existing member and hope that the new gain would outweight the loss. However, I don't really see why they can't do the same with just adding members without replacing anyone. It doesn't make all that much sense.
Lastly, I think that doing just a bold announcement of replacing a member and then adding 'maybe' and 'perhaps' is a bit misty as well. The way I see it, replacing a member should have been a tough decision and a well calculated plan, which does not fit with the current ambiguity of the announced 'maybe'. You don't go about your employees and say 'hey I'm thinking of firing you, maybe', unless you're absolutely sure you'll fire him. With that in mind, I'm closer to believing that they are just testing the waters to gauge the people reactions. I don't think I can accept a different reasoning.
Guess I'll have to wait a couple of days more. T-ara hwaiting!
