Bethesda's PR manager Pete Hines responded on Twitter to a claim by gaming sites that the Xbox One version of Fallout 4 indicated that the install size would be around 28GB.
In a Twitter post, he, "we haven't given out file size or system spec info for any platform.", despite gamers telling him their Xbox One preloads showed a 28.1GB download.
Hines also let gamers know when the PC system requirements would be revealed,, "we usually release system specs about a month before launch."
Gamers who loved the Perk Poster shown in a Beth Blog were also, "In case you missed the PS at the end of the article, pre-order Fallout 4 and get this Perk poster w/ your game."
Fallout 4 is due to be released on 10 November 2015.
