Standard Goldwing is not listed for 2014 either and the ST1300 has not been changed since 2012 and still listed as such but still available and on the Honda site, I think you will find that Honda USA are going to be pushed more like the rest of the world with model changes every few years not every year, in Europe when you buy a bike its registered the year it was sold not the model year so theoretically a 2006 GL1800 could be sold brand new today and classed as a 2013, the rest of the world is not so fixated with model years just a new bike is a new bike.
Bet we dont see a change for 2-3 years and I doubt it will be the significant upgrades people mention like ABS and reverse as far a Honda are concerned you can go buy a full wing
