Kaik -
As Finkel had said, WT will drop 1914 entirely and will deny that had ever mentioned Jesus return in that year. Many JW will node will not worry about it, because it is a new light. The issue for GB and WT is to find another resonable date, and model various date calculation to it.
I get the feeling with the way the WBT$ has dumbed everything down that the 1914 scam will just be swept under the rug.
I also feel they won't set another date or make calculations either because the internet will expose their stupidity (as usual).
They will hope it all just goes away. If they have to there will be some hilarious 'new light(TM)' for us to split our sides laughing at......rather like the 'overlapping(TM)' gag they showcased.
