My theory for Sigmascape

[Melichoir]

Personally, Ive been under the impression that Omega weapon will be a "Best of the Classic FF" bosses. So that there isnt exactly going to be a huge rhyme or reason for the lettering (Delta, Sigma, ???). I mean there probably IS a reason for the Greek Lettering, but its probably more an abstraction or a wink-wink-nudge-nudge than some deep philosophical meaning.

That being said, youre more likely to see bosses from Final Fantasies that were note worthy. So my prediction is youre more likely to see bosses from...

FFVII
FFVI
FFVIII
FFX

Bosses from these games would make more sense, since theyre more iconic and widely known from the FF games, and FFXI, FFXII, FFXIII are to 'recent' as titles, and the earliest FFs were already semi represented with Deltascape.

Of course, they could also be operating by systems. So Deltascape was FFV on the SNES, Sigma could be a Playstation Title, and the last of the Omega could be a PS2 Title.

OR They couldve named it Delta because V and the Delta symbol look similar, so Sigma could be FFIII cause you know, similar looking.

They're named this way because of Omega himself, named after a Greek Letter

Well I got that, but why particularly Delta and Sigma, and not lets say Phi, Theta, Kappa, Alpha or other Greek letterings?

so Sigma could be FFIII cause you know, similar looking.

Problem with that is the Crystal Tower raid has most of the noteworthy bosses of FFIII in it.

[Lilseph]

The only way to find out at this point is to wait till Sigma and see if there's an actual pattern. I personally think it's just a fanservice series of raid, and I'm okay with that. Just gib IV, VI and VIII.

My theory is basically this omega is based off Final Fantasy record keeper and it even states on that game.

"Final Fantasy Record Keeper is a free-to-play social role-playing game where players participate in memorable battles from the Final Fantasy series"

Maybe added chocobo dungeon character and boom bam its a way to bring old bosses into the game.

O5s- Kain
O6s- four fiends
O7s- Golbez
O8s- Zeromus

i assumed the second tier raid would be against hero's since omega made that a big deal after the trials.

omega wants to fight the strongest thing ever which technically would be hero's strong enough to beat other hero's.

so tier two would be hero's and three would be omega. besides story wise they could do some cliche were we fight each other then help each other beat omega.

[Nestama]

"Both Halicarnassus are named for the entity in the story. Omega's is actually more accurate, considering he made it as accurately as possible, while the one in Haukke was just named by a frightened passerby."

Something along those lines was said during the lore panel thing in PAX West.

It probably will not happen, but I would love to fight the heroes from FF5 next. They could phase between jobs altering mechanics.... it would just be a cool change pace.
