I think FO4's Goty will be out in November of this year, given the aggressive release dates they are announcing for its DLCs. The first is in March, and the next two following a month apart. So that's about 6 months from initial release to final DLC. That gives them 6 more months to slap it all into a GOTY edition for the Christmas 2016 rush.
From what I understand
Far Harbor isn't the last planned DLC. Bethesda has repeatedly stated that they plan to release "new Fallout adventures and features throughout 2016." They haven't said how much more specifically, but they have said that they believe the extra content (whatever it turns out to be) is worth "$60 at least." I presume that was why they felt justified in raising the price of the season pass to more than the three announced DLCs were worth. They have already scheduled their second ever press conference for E3 this year. I expect we'll learn more about
Doom,
Dishonored 2 and further
Fallout 4 DLC and console mods at that time. There's no real compelling reason to come out and announce anything else before that.
I guess we'll just have to wait and see.
