I think Metal Gear series would never end, if Kojima would stop making the seiries (Which he has).......someone else would go on with making the series. It'll be like that, well atleast it SHOULD be like that.
Just because Kojima is tired with Metal Gear doesn't mean we fans are too.
But I still have find out who is directing this 3rd chapter, and if it turns out to be Kojima, I will never trust him ever again.
