If Kratos does come back, i hope they work on the story a bit more and give Kratos some personality like what was seen in the first two games, because in prt3, Kratos was an empty shell....the only thing he really stated in that game was "only zeus death matters"...
TBH...the third game wasn\'t really crafted well story-wise....i mean i know kratos character isn\'t really a good guy, but he really isn\'t truly bad either, but in prt3..at times i just felt like kratos was pure evil...i really couldn\'t see what the gods were actually doing wrong (the writers were supposed to show that and they didn\'t) and then they tried to give kratos some type of sentimental emotion towards the end which felt completely out of place.
I know the main guy from the series the created god of war left the series for the 3rd version and it showed alot....maybe not graphically, but story-wise and character development-wise prt3 was missing alot of substance...
