Well, considering that support for FO4 will stop in 2017 (Got that from some interview with the big cheese I saw online), and the fact that we're already two months in to 2016 (Yay! Christmas is only 10 months away!), I'd guess that all requests at this point are fruitless.
It would take too long to put anything brand new together at this point. Getting together voice over people, animation, artists, and having them go at it from scratch for a new release on top of what's coming, and be done with it all by some time in 2017, I just don't see it happening. And he didn't say at what point in 2017. It could be by the end of the first quarter they will be done. Who knows.
My gut tells me that they are just finishing up all planned DLC and are working on patches and will be addressing any new issues introduced by the coming DLC. I seriously doubt anything new is going to be considered at this point.
