I think BBT taking over another bank is more likely than it being taken over. Many current shareholders are like yourself: long term holders who are looking ultimately to a return of share price and value. I don't think any organization is going to offer that kind of premium. Possibly a bank with huge upside potential itself might be a good candidate for takeover but there are few of them: JPM.
More likely is BBT taking over another bank. I hear much more about RF than STI. Perhaps KK is light on the trigger because he knows more about the coming problems than we do. In other words, he sees the price of them (and BBT) coming down; maybe way down.
