I think it is very possible that the whole 1914 date itself will be minimized probably starting this year, certainly by the 100 year anniversary of 2014.
It could easily be done by just not mentioning it any more in the current literature - much like they put an end to the 7,000 year creative days.
Then, the emphasis could be a "signs based" eschatology, as was mentioned above.
Really, a 100 year old "sign/time of the end" is pretty long in the tooth to keep on hammering into the next century.
