Could you elaborate some more on the other ones, and how they tell something about a bigger story?

-Color coded networking
-Missions being coded CAT1, CAT2, CAT3, CAT4. Wondering about Catalyst being CAT5, and Citadel DLC being CAT6 (aka technically 'after' ME3, from a certain POV...)
-Silversun Strip being the most colored content in the series. Red. Blue. Green. Yellow. Cyan. Magenta. All fitting various themes. Art. Painting. Creativity. 
-CAT6 mooks and the first outfit of CloneShep have CYAN coloring. They also have the same near-exact logo as the 'crashed ship' in Leviathan DLC. So...why? No reason? Leviathan also have CYAN eyes and overall coloring in their scenes.
-Leviathan's enthrallment scene is incredibly similar to the meeting with the Catalyst.
-The Convergence video accurately portrays what I think is happening. We start off opposing Sovereign and trading smacktalk. We may, optionally, end up allying with him and coming to an accord.. of sorts. Yes, I think that Sovereign is the Intelligence (just using a FULLY synthetic "Reaper?" to travel the galaxy with), experimenting with organics to eventually find a better solution to its programmed directive.
This Cycle may be much more similar to past ones in ways that most may not realize, but it's also different, and carries a true hope for the future. The Cycle has ended. It may be broken. And the Reaper threat has been defeated. And Shepard is a legend.
