Updated, wiki'd and more photographs.
I have been told that the lounge is due to get a re-fit in June, independently of the BaxterStorey changeover. This is to brand it in the British Airways style (though personally I don't think there is much wrong with it). So I suspect the writing is on the wall for the greyhound photos, unfortunately. The lounge will not close, it will be done overnight(s).
I think there is a case for saying that this is the best lounge in BA's network, with the possible exception of the two Concorde Rooms. Not so much from the catering point of view, but given it has showers, lounge beds and power sockets everywhere it is very comfortable and well designed. We can thank Lufthansa for their generosity.
