You don't need to be a fanboy to think that they will release this year, you only need to appreciate the advantages of a digital distribution

.
If you look at the kickstarter page, the list of intended features is considerably shorter than that found in the DDA; for example, there is no mention of passenger ships or mining.
Once rankings and reputation are added in Beta 2 (according to Newsletter 38, or possibly 37), we will have pretty much everything we need for the core game, with the rest of the stuff adding variety and balance. So I reckon that they will release the game with a subset of features that are working well by the end of the year.
Of course it's not realistic to expect everything in the DDA to be implemented to high quality in the next 4 months... many features can be added in free patches over the course of 2015
