Ok guys, lurking these forums for the last couple of weeks has been quite amusing. The entire clock theory, all the troll posts, pretty entertaining. Anyways, I think we just need to pay more attention to the quotes. Particularly Maxis' quotes, because there's less of them and they all pertain to the easter egg.
Let's look at one quote in particular
"Yes, the spire is online. Now if the other sites could only be likewise, and powered then there is still a chance to complete that which was begun so many years ago. Your help has been invaluable. Farewell."
Now, doesn't it sound like there is more than one Spire? Theres also 4 pylons in Green Run, two of which are knocked over. However there is another accessible pylon that we need to experiment with. I think that we need to repeat the easter eggs based off of which side we did most recently. Just like how Shangri la was repeatable with no instruction after you finished it the first time, I think that we may be able to activate the other pylon, and maybe even the church. So if you recently did the Maxis side, then lay two turbines under the other pylon and emp an Avogadro under it, then place the turbines at the corresponding street lamps again. Same deal with Richtofen, just lead a train of zombies under the pylon and "make them go boom". After a round or so head 4 streetlamps and emp them all at once. If the second pylon lights up, then we will know for a fact that the spires are the trichonomous system. The only difference between the two pylons is that one has an obelisk table, which hasn't been used for anything yet. So I think it's worth a shot.
Of course this is all just theorized, but there has been a repetitive nature to the past couple of easter eggs. Like in moon, how you had to fill up all three pyramids with souls.
