There Isn't a Huge Gap Between PS4 & Xbox One
The Fallout 4 mod release for PC in April represents the first stage of Bethesda's roll out.
The developer is also going to be rolling out mods (not the mod tool, that's PC only) for the Xbox One and PlayStation 4. Howard has shed some light on those releases as well and they aren't as bad as I initially thought they would be.
If everything goes according to plan, Bethesda will release Fallout 4 mods for Xbox One in May followed by mods for PS4 in June. This is big when you consider Howard's comments from last year.
I think a lot of people (myself included) were worried that mods would land for the PS4 months after the release for Xbox One.
So, unless the company runs into some snags along the way, you can expect Fallout 4 mods to grace all three platforms in the first half of the year.
