That changed today with an announcement from the company on plans for continued game support after Fallout 4 launches in November.
I'm glad and relieved to see that a company has not announced that they plan on abandoning their consumers before
the product (and its DLCs) has even been shipped.
The first phase will come through game updates.
For anyone with experience with Bethesda / Zenimax's large open world titles this is a funny, oh so obvious statement. Frankly we can expect the first patch released within the first week of release, going by the Bethesda / Zenimax's Fallout and Elder Scrolls. My bet would be day 1-2.
The news of mods being available for consoles is a new, interesting, and positive tidbit.
