I still secretly hope the PS360 versions get put on hold and Kojima and his team can fully focus on next gen. Given the huge PS4 sales for GZ that would be an awesome thing to do. Cross-gen is the absolute worst.
But ultimately this is Konami, so this will never happen.
I don't blame them. They'd be missing a lot of money that way.
Ideally though they would see GZ as last gen's taster for the next-gen exclusive.
