Some more info shared by Cory Barlog:
-The gameplay is being re-imagined, but the storyline is being continued within Norse Mythology.
-We play as Kratos for the whole game.
-The game is set “many years after God of War 3"
-It’s a much more intimate and player-controlled experience.
-The accessibility should be the same as previous game, but the gameplay is totally different.
-It’s a big game, but it’s not an open world.
“More to come” on more characters that will be included in the game.
-The game will be released “soon,” not this year.
-Quicktime Events won’t be included in the same way they were in the previous games.
