One of the icons on the UI has its name blurred out (in both the pictures that portray it), obviously meaning that it’s something Ubisoft still doesn’t want to reveal.
If you look at the screenshot normally, you may not find the probable easter eggs easily, but turning it upside down the symbol of the Assassin Order (or something extremely similar to it, down to the angle of the design) from Assassin’s Creed is unveiled. In addition to that, the two elements under the glyph definitely resemble the shape of the Pieces of Eden.
This adds some solidity to the theory that alleges that there’s a connection between Aiden (and Watch_Dogs) and the Assassin order (and the Assassin’s Creed saga).
Below you can see both the original screenshot and the flipped version, with the Assassin insignia overlayed.
Of course we’ll probably have to wait and play the game to be sure of the connection, but as a fan of the Assassin’s Creed series I can’t say this isn’t intriguing.
