Okay, so Activision has just updated the official website with some new information and the digging operation had to commence. Basically, Toys For Bob is now credited for their development support and porting the game, alongside Iron Galaxy Studios being mentioned for their effort on the porting (unknown exactly which version of the remakes, but assuming it’s like Skyrim Switch, then that’s at least a safe bet). We’ve also got the new boxart for the Xbox One, Nintendo Switch and PC (Boxed Steam Download) versions of the remakes. Xbox One is notable for having Xbox One X support, HDR and 4K, Steam and PS4 versions having support for 4K.
Edited the report to clarify Toys For Bob’s involvement post release of PS4 version. Also, it is important to note that Toys For Bob is handling the Switch Port, Vicarious Visions for the Xbox One and Iron Galaxy for the Steam (PC) port on Windows (Not credited on the store page, but they are on the official website).
There is no information yet on proper preorders for each version of NST.
Have a look at the boxart for each version in the gallery:
