No the 1914 doctrine will not change.
The JWs will milk for all it's worth the "wordly" centennial observances of 1914 and the JWs' literature will loudly declare, "We alone foretold the significance of 1914".
In so doing, they will do what they are unequalled experts at doing: L eave out the significantly embarrassing bits and make it seem like "truth in action".
It's all Impression Management.
We will watch from the side-lines astonished - and frustrated? - that the rank and file and "newly-interested-ones" assert how much closer we are to the end.
