Many people may have noticed that Hideo Kojima has been rather Twitter-happy as of late. Even to the point of teasing a new "taboo" game in the making. Speaking in an interview with Famitsu, however, Kojima's next project may indeed be Metal Gear Solid 5.
In the interview, Kojima was still unsure if it would definitely be the next Metal Gear Solid, saying that "for the next game I make, it's either MGS5 or an original game. I only have these two choices."
Kojima Productions currently has several games under their belt, including Metal Gear Solid: Rising, Metal Gear Solid 3DS and Castlevania: Lords of Shadow. Nevertheless, it seems that Kojima is still working on something outside of these titles as well as putting the best of his staff to work on it.
As for Zone of the Enders? Kojima jokingly revealed, "regarding Anubis and so-forth, sorry -- those will be pushed a bit into the future. I'm 47 this year, and I don't know when something might happen (laughs)."
