Why not read the whole of the announcement on the FJE website?
That seems to make it clear that the 2 757s have been contracted until October 2007, and the contracts will be honoured. I can't see the airline telling its clients (tour operators) that the aircraft will operate from different airports.
I can't imagine there are too many charter airlines with definite, publically available plans for winter 2007-8. They will no doubt follow in due course. The FJE boys and girls seem to have a more assured future (according to their employers) than many charter airline staff.
So chill, and enjoy the ride.
