There's a somewhat irritating lack of Metal Gear games on modern consoles, but a recent listing could hint at that being rectified pretty soon.
Armature, the developer of the Vita version of the Metal Gear Solid HD Collection, currently lists "PS4" under the list of platforms it's developed the port on. This might hint at a future announcement of a PS4 version of the game. However, mistakes like this can happen, so take this tidbit with a grain of salt.
With Kojima out of Konami and working on Death Stranding and most of the spotlight currently falling on survival-oriented spinoff Metal Gear Survive, it makes sense of Konami to begin looking backwards for new revenue. We've reached out to Konami for a statement and will update this article should they reply.
It'd be nice if the collection game to PS4, but I'd also like it on PC, please. Also, while I'm asking for Metal Gear things, I'd like a remake of the first Metal Gear (not Metal Gear Solid) on modern platforms that uses the MGSV engine. Thanks!
