Update:
Armature has told DualShockers that the listing was a “typo” made by the studio’s web developer, which is in the process of being removed.
Original story:
Armature Studio, the developer of 2012’s Metal Gear Solid HD Collection for PlayStation Vita, has listed a PS4 version of the game in its portfolio. First discovered by Reddit user naninho205 (via Game Informer), the platform listing appears on Armature’s official website (check out a cached copy in case it’s removed).
naninho205 also made the following observations:

Armature previously ported MGS2 and MGS3 to PS Vita (Peace Walker was left out) but the studio’s website displays images from all three games.
A headline on the page reads “Archived Game Content Coming Soon.”
Take all of this with a grain of salt, however. Neither Konami nor Armature made anything official and the listing could be a mistake. As usual, we’ll update our readers when we have more info.
In the meantime, check out our review of the PS Vita version. PlayStation LifeStyle’s Paulmichael awarded it 8/10 but also noted:
Ultimately, the incredible amount of fun and content to be had within Metal Gear Solid 2 and 3 outweighs a lot of this package?s negatives. But the lack of Peace Walker is such a glaring omission, it really cannot be dismissed all that easily.
Would our readers want a Metal Gear Solid HD Collection on PS4"
