The North American PlayStation Store may have revealed the release date for the upcoming God of War title.
This should be taken with a grain of salt and the information has since changed by for a short period the store listing stated the release date as 22nd March, 2018. What is interesting about this date though is that the original God of War on PlayStation 2 released in North America on the 22nd March, 2005. It is just a theory but there could be some truth to this given the weight behind that date.
God of War was revealed as an "early 2018" release exclusively for the PlayStation 4 but with PlayStation Experience happening in a few days, we might see an announcement.
