Just my prediction of the potential plotline for the upcoming Splinter Cell Omega Protocol (I hope we get a trailer sometime soon instead of hints of development through crossovers in other Ubisoft and Tom Clancy franchises.)
------- SPOILERS FOR SPLINTER CELL BLACKLIST AHEAD !!!!
So the Blacklist was taken down, American Dust was prevented, and Majid Sadiq is secretly in custody to be questioned while the world is told a lie that he died. We won... right?
WRONG !
Sadiq is cunning, thorough, and a man who's is Bismarckian in the idea that he has backup plans for his backup plans. In Blacklist, he found out about the existence of Fourth Echelon and even the names of it's assets.
The Sub-Title of "Omega Protocol" could be referring to the idea that there is a major breach in security. Sure Sadiq is contained, but the majority of his faction isn't. And since they are without their leader, they might be instructed to leak the intel about Fourth Echelon across the globe, and even possibly Third Echelon.
I predict that Omega Protocol will be a game where the immediate target isn't America or another nation, but Fourth Echelon and the NSA itself. The goal of the story would be to prevent data from being sent out into the world-wide-web in order to maintain state secrets of black-ops that go against things like the Geneva Conventions. Failure would not only mean that Fourth Echelon would be disavowed, but that it's members would be put to the sword or eternally imprisoned. Pardons are not allowed should classified intel is known as common knowledge.
Plus there is the added threat of the "12 Nations that stand behind the Engineers" that Sadiq boasted. Could that be a bluff? Or is there really a Zodiac Conspiracy?
I predict that the above would be the main story, and the investigation of the legitimacy of this Zodiac Conspiracy would be either Side-Ops or a DLC Expansion.
Mikhail Andreyevich Losokov, formerly a member of Voron under the callsign of "Kestrel", is now a member of Fourth Echelon. In the game Tom Clancy's Elite Squad, Kestrel is given an updated appearance and is allied with Fourth Echelon, not Voron. IF this is canon, then it is likely that after the events of the novel Splinter Cell Blacklist - Aftermath, then Kestrel joined with Fourth Echelon.
Either as a DLC or a Side-Ops sub-campaign, we might play as Kestrel as he tries to find out who was behind the events that lead to the death of Archer, Echelon Agent / Trusted Friend. Of course, that would lead to some inner conflict with Andriy Kobin being the man who shot him and Kobin being an asset of Fourth Echelon. This could lead to a choice to be made to spare or kill Kobin, but ultimately I think Kestrel would remain part of the team to hunt down the group known as Megiddo.
Crossovers?
Definitely Rainbow Six and Ghost Recon. Possibly H.A.W.X. ? Of course it would be cool for a Metal Gear homage crossover (non-canon obviously, but a fun event like the Predator and Terminator stuff from Ghost Recon)
Time Period for the story would likely be 2014-2016, considering that the Blacklist has been taken down in the Winter of 2013 and this would be an immediate threat with the detaining of Majid Sadiq.
EDIT :
Due to a Sniper Rifle from the Splinter Cell crossover in Ghost Recon Breakpoint, it looks like Sam's daughter will be an asset of either Fourth Echelon or Paladin Nine... mainly due to the fact that the Paladin Nine SNR rifle has the description of being "Sarah's signature weapon".
I wonder what dynamics between Sam and his daughter will occur.
"I told you NOT to be a soldier!"
"I became a Sniper so I am very far from the action dad."
"...alright...its just... I can't lose you again Sarah."
"I know dad. And I can't lose you either."
*loving family hug
"Which is why I will be providing overwatch on this Op."
*Sam's expression changes from a loving yet worried expression to an "Oh Hell No" expression
"GRIM! Why isn't Briggs the marksman on this mission!?"
"Because his arm is still out of action and quite frankly, your daughter is quite the marksman."
Should be interesting.
------- END OF SPOILERS FOR BLACKLIST
Soooooo....
This is my basic prediction to the story setup of SC Omega Protocol. Perhaps after this one, they might have one that would be set up so Fourth Echelon would focus its efforts of the Megiddo organization. Perhaps Megiddo are those who are behind the Zodiac Conspiracy that supported The Engineers?
Thoughts anyone?
