Good questions! There are a host of rumours going around, but (after many false reports) it would finally appear to be true that the '4 Engines 4 Longhaul' straplines are being removed from the A340s (the line never appeared on the Boeings). I suspect that there might be an announcement at Farnborough next month, but B777s, B787s, A350s or A330s.... ?
