Oh thank god. God of War creators confirmed that Kratos will be alive and Kratos's adventures in Norse Mythology will take place after God of War 3. The game will be a  soft reboot for the franchise and will take the series to the world of  Norse mythology—all previous games were based on Greek mythology.

So it's not God of War 4. it's just called God of War (PlayStation 4).
