During an interview with French IG Magazine , Kojima confirmed there will be a Metal Gear Solid 5.
According to PSM3 magazine ,they revealed Metal Gear Solid 5 will take place in Africa around the 70s featuring Big Boss and possibly live the moments of creation of Solid Snake.
Kojima is trying to gather alot of clues for Metal Gear Solid 5. An important clue lay in Big Boss poster “Big Boss needs you” “Diamond Dogs.” We have no idea what this mean but we will import a picture of it down below.
Kojima being a fans fan of David Bowie perhaps his referring too his album and have something to do with MGS 5.
