The release of the new story trailer of Watch_Dogs has caused a lot of controversy within the gaming community, due to the fact that many simply feel that it doesn't look that good. Some initially thought it showcased the last generation version of the game, but from what we can gather, it definitely seems to be the PS4 version, even if Ubisoft seems to be covering the tracks.
One thing is for sure. Many have seen an extremely compressed version of the trailer, utterly ruined by YouTube. Watching lossless screenshots from a 1080p, very high quality of the trailer shows little details that might have been overlooked, leading many to misjudge the visual quality of the game.
