I believe that the sale fares have now been further reduced!
I was looking at the LHR-DXB economy fares today for a work trip in November. Although the BA and VS prices were identical this morning, by this afternoon, VS was coming out to be £40 more than BA (as BA reduced its price). I did notice yesterday that the DXB economy wasn't on the list of destinations for sale (though VS was running middle east offers just before the sale).
I had some faith in the VS revenue management department to react to the price difference, and had held off the booking. having just checked the VS sale page, Dubai has been magically added to the economy sales list, with PE fares reduced from 719 yesterday to 669 now. I have also noticed a few others that have been further reduced, including Tokyo, Shanghai and Hong Kong (and probably others).
Sorry for the long winded explanation, but I wanted to flag this in case it would be of help to someone

if you had written off the sale yesterday, it might be worth another look.
