Sad news as I really too like the A380 and specifically the bar which I have found to be one of the nicest flying experiences I have been fortunate to have. I think the days are numbered for F which if you can believe what the chief has been saying was to be removed in preference for revised J class - enter Q suite. I think this decision about the A380 will put to bed any desire to reconfigure J class with a version of Q suite , however on the upside I would imagine both the Bar and F class will remain until the aircraft end their service.
I cannot see them starting another all Premium route to London or anywhere else, that was trailed and not that popular in the end , however it did secure another slot for them at LHR where eventually it was utilised by a normal wide body aircraft.
