Speculation: The image of the Terminal.
Isn't there going to be terminals in Halo 3? Could they possibly show us videos that would continue in this fashion? Like explain the flood more? That would make sense.
But where does that leave us now? Assuming thats how that aspect is wrapped up (explaining the birth of the flood), what do we do?
SOTA seems to be the last piece of the puzzle left unsolved.
Adjutant Reflex was hijacked by this new entity. They merged. They broadcast together in the form of Transmissions in Forerunner servers. They've been leading us to all of the servers.
Surely SOTA wasn't just for finding Server 1...right?
Something's going to have to happen..."More Records Remain...we shall soon see what we shall soon see...The Next movement is set to begin..." Could this all be speaking of Halo 3?
In some ways I could see how Server 5 could be the end. But I don't feel satisfied enough, because we're lacking closure.
Then there is this file:
You asked me once, what happened to those who vanished?
You asked me, why did we survive where our fathers fell?
You wished to know how we ever let it happen
A scourge that consumed the galaxy
And the cure that was worse than the cancer
You asked me once about my intent
And the spot that would not wash out
I promise you the answers lie in the Ark
Find me there in the dark
For that is where I abide
Bridges the gap to H3 nicely. Meeting Forerunners at the Ark.
The future of Iris is uncertain...
