Compiled by NeoGAF user, (ahem) Bitch Pudding , three major details have been pored over. The first is a hovering, ghostly figure in the trees behind Kratos' son, which promptly flees when they approach:The second is a flitting, seemingly armed flying creature that passes overhead as Kratos enters Dauthamunni:Finally - and most deviously - what looks like a river in the background of the final shot actually appears to be a landscape-spanning snake, leading people to speculate that we're seeing Jörmungandr, the World Serpent of Norse Myth:Want to have a look yourself? Skip to 3:34, 6:46, and 9:15 respectively in the trailer below and see what you can spot:Since these were pointed out, other little details have been shown off in the same NeoGAF thread , including what look like Hermes' boots lying on the floor of Kratos' cabin, scuttling creatures in the trees around our heroes and this huge, scampering wolf:God of War was our runner-up for the Game of E3 , and this trailer alone made some of us care about the series for the first time . A release date is as-yet unannounced.
