I'm going to just talk out loud here, and hopefully someone will correct anything that is wrong, in particular regarding the timing of events:
Trailer releases, first ruins found very quickly.
Not long after, the layout is changed, with no apparent explanation. We also get the first indications that we were not meant to find this site first, or perhaps not even early in the process.
People spend time, but not a lot of forward progress. Time passes, and Ram Tah's CG is put into the game.
After the CG, Ram Tah has been able to identify more systems. This, coupled with the change in layout, implies that there is something to figure out, but we failed to do so.
More ruins are found in these systems using brute force methods, with one different layout, and a few similar to the first, or exactly the same.
Galnet message involving Melville, who indicates that he has found the key. More systems to search, and more implication that there is something to figure out, and we still have failed to do so.
I've said this before, but it is my belief that the key to this puzzle has been staring us in the face since the beginning (more accurately, since the layout change), but our focus has been elsewhere. If someone can think of a legitimate reason for changing that layout other than what I believe has been implied, I would love to hear it. I can't think of any reason other than the possibility that the original layout would have led us to a dead-end, if we had figured it out. I think this is very compelling evidence that has largely been pushed off to the side with the advent of the drop-zone method.
I believe there is a cypher here, and if we are able to figure it out, then we won't need any more drop-zoning.
I welcome any discussion, critique, or challenge to this hypothesis. I am quite certain that I am far from the first to consider a cypher, but I feel it has been forgotten or neglected, and I think we need to examine it again.
