In year's past DCL has announced known itineraries (Caribbean/Bahamas) in the Fall and newer itineraries in the Spring so you don't always get the same amount of lead time.
I do agree that January 2014 should be all known itineraries, but DCL has never put themselves in this position before. They have never made such a egregious pricing error as they did in 2013 and they are not sure how to get themselves out of this position.
Typically pricing would be low when first released, but that was not the case for 2013. On day 1, the pricing was almost doubled in my case. In 2012 I was able to get 2 Cat 4s with 4 people for $7,800. Those same 4 people in a single Cat 4A was $7,600 in 2013. That is an insane price increase when you consider that the 2013 pricing takes into account 3rd and 4th passenger pricing which is always much lower than 1st and 2nd.
DCL screwed up royally with their 2013 pricing, they know it, and are trying to figure out what to do.
Our first DCL cruise was 2002, I have followed pricing very closely for the last 10 years and the price increases for 2013 were by far the most insulting. Luckily for many of us, it didn't go unnoticed.
