I don't think they should continue Kratos's story, but they can resuse the IP to introduce a new series of games using the same style of gameplay.
A bit like Bioshock Infinite or Final Fantasy. They can keep making new games using the same style but using characters in a new continuity.
I think that would be good. Personally, for me no more Kratos. The story has become beyond boring, and its time for a change.
Santa Monica is a studio I think should have two games in the pipeline something like 'God of War Infinite' and a new IP.
