What's in the middle of the triangle?

[Chemicaledge]

So we have three maps that feature the four current main characters, and each map links to the next via a nav card/card reader combo. Each card reader is located very close if not directly under the tower on each map.

What if these towers are being used to locate and/or power a fourth location?

Of course that raises that question of, assuming this theory is correct, whether the fourth location is something that we already have on disc and finishing all three Easter eggs on the same side and installing all nav card will unlock it, or it's simply the final DLC map. Of course if it's simply the final DLC it would seem that there would have to be a significant map difference to justify the massive lead up, kind of like how you couldn't do the moon easter egg without having done the COTD and shangra-la Easter eggs first.

What do you guys think?

Or do the three towers form a pyramid when the point of a fourth tower passes by on the moon that isn't a map but allows the release of the O4?....

I have went through all the files and there seems to be no sign of any "extra" maps anywhere, except for the fact that there's a stub map that is filled with the next DLC , the stub map has DLC name, so

You can't really tell the name of the next DLC.
