The last trailer we saw was pretty jarring, as it had graphics that were way worse than what Ubisoft originally showed.
Someone made a gif to showcase how graphics looked then and now.
The latest trailer they showed:
People are hoping it was the last gen version they showed off. But how many times has Ubisoft done that in an official Watch_dogs trailer ?
Also, according to Playstation Denmark, it was the PS4 version being shown in the last trailer O_o
Another fact why the last trailer was from current gen versions and not last gen: The trailer was in 1080p and the PS3/360 footage could not be recorded at that resolution.
Prepare to be underwhelmed
