ChewyWeAreNotHome: There was an interview today with Sean Murray to promote the July 24, 2018 release of No Man's Sky NEXT for Xbox. Since this was for Xbox there was no mention if other platforms will receive the update at the same time, earlier or later.
The link that I first posted apparently has audio cutting out halfway through so another link is

There was no discussion of existing games, saves, other platforms, etc. The only gameplay discussion was of multiplayer.
As long as MP is opt-in, I can see ways that it wouldn't suck -- as well as many, many ways that it could. They'd certainly have to find some way to lock it down so that the guys with mods aren't running S-class fighters on day one.
I finally got to the center of Euclid the hard way and was surprised / not surprised to find that many of the systems on the edge of the center had been discovered within a few days of the game's original August 2016 launch. Fine, whatever, off to the Hilbert Dimension I went.
So, put us all in real-time in the same universe without better security on hacks? Ummm... no thanks.
