Any connection to present day from past games? [SPOILERS]

When we left off the real world in AC3, Desmond has apparently died while releasing a potentially evil spirit onto the world, all the while the end of the world was coming. Does it bear any relevance in AC4 present day story or is it like "Desmond? Come on guys, you said you didn't care anyway. Go play some pirates, arrrrr... yarrr."? Also known as spin-off...
