I think Horizon is a late q3/early q4 game so think that State of Play is July earliest but who knows.
I've heard it's a September/late October release. So unless they want to overlap state of plays for kena, we should see it more June/July for Horizon. WHich is what Grubb is reporting. Which is his estimate, but I would argue backed by things he's heard.
Which is similar to what I've heard.
I do know Sony has couple big announcements. But if they are ready for the main E3 state of play is something I don't know.
