There are some rumours that the Fed might change the language of the extended period, perhaps to 'some time'. I find this doubtful, the economic data is not supportive. NFP has been weak, inflation has been low, inflation expectations are still quite anchored. The Fed doesnt care about the fx value of the USD(Whether they should or not is irrelevant).
Most important there was no dissenting vote in the last fomc calling for that, they seem likely to only gradually start to consider that, the fed is not fast moving(In the meeting after Leh failed and the stock market had the worst drop since 9/11 they kept rates at 2% complaining about inflation). If anything they are likely to start teasing the idea of changing the language but the actual change is likely to only come in 2010
