This must have been said before but is the easter egg not already fully revealed for the standard game? We already have the biggest achievement in the game (75 gamer points), does it make sense that there is something even more complicated to find after this?

There will be explanations to come for the nav cards but in my opinion they will be used to link Tranzit to the new maps in forthcoming DLC's and are therefore useless at the moment.

Or is this the defeatist view?
