Well Murray did say the following around release:
I agree though that this is speculation only and shouldn't be treated as fact. Could be that NDA prevented them from saying anything about missing features. Could also be that they just didn't handle communications correctly because they fucked up. Who knows.
Yeah, actually there was an interview like a day after PS4 launch where someone was asking him about the Xbox version, and it went like this...
--------------
Xbox One owners understandably could be a little jealous that a game of such incredible possibilities hasn't been released on the Microsoft console.
However whether the game is a PS4 exclusive or whether this was a timed exclusive that might one day come to Xbox One.
So when we spoke to Hello Games Sean Murray, the man responsible for creating No Man's Sky, we asked him and received a rather coy response for what we assumed was a very straightforward question.
In response Murray told us he wasn't sure what he was "
actually allowed to say" at the time, noting that he needed to be
"very specific with my words".
Before going any further though, Sony's rep stepped in to move the interview along, explaining that at this time there was nothing more to add.

Sony definitely had a lot of power in controlling what he could talk about.
