I'm afraid that hasn't been confirmed yet.

they said it would make its console debut on playstation. its almost definitely coming to xbox one. and definitely coming to pc

They haven't denied it as well.
Its probably some contract with Sony to remain focused on the PS4 version before announcing the PC and X1 versions.

In that article they say that No Mans Sky will have its console debut on PS4, clearly indicating that X1 version is coming as well in the future.

An official announcement isn't required when they have never denied a PC/X1 version won't happen.

NMS is coming out on PS4 first so I'm going to play it asap, and I'm not gonna wait for other platforms that gets it later or never.

Come on OP you didnt get the memo aparently, no matter what you post or how many exclusives PS4 anounces, ppl will say theyre uninteresting and PS4 has no games.

Well we definitely for sure don't know if an X1 version is coming. I can see where folks will get that notion though. However, A PC version is....expected to say the least.

All I'm saying here is that no one here can keep saying multiplat if none has been announced yet. Although we can all be sure a PC version is coming. For now though, it's only exclusive on PS4. There's no other way to spin that. This is not me saying that it will never come to Xbox One. I'm just saying it wasn't even hinted that it's coming.

look, no man sky is made by a small company. their focus is on ps4 right now. if they ever make it multiplat then you better believe that its going to take a while.

Some nice games that are coming in the FUTURE, but that just means I can easily wait until all these 9 games are out before even remotely thinking about getting a PS4.

From a advertising perspective this does very little to encourage me to buy a console.
