Originally, No Man’s Sky was a PlayStation 4 and PC title; however, during recent months it seems that the PC version was forgotten about or placed on the back burner without any official confirmation. During the E3 2015 PC Game Show, it has been reconfirmed that there is a PC version and that it will be released at the same time as the PlayStation 4 version. This was announced by Sean Murray of Hello Games.
No release date as of yet, they apparently aren’t allowed to announce that just yet.
