Nah they need to fight this year, were only in May... There is too much money involved for it not to happen and Fury especially I believe has had alot of financial backing and money laid out to him from various people and they will all want repaying and the AJ fight is THE money fight for them to recoup that... Plus AJ and Fury are both in their primes...
If they dont fight this year it wont happen, as mandos will be called and the belts split up... It will go from one of the biggest fights of all time to a mythical big 'what if' or 'what could have been fight...
