@Daemos - I think the only reason why they would go all out for a second story, instead of waiting for SF6, would that it would serve as an official transition from SF5 to SF3, and the SF6 story would go beyond SF3. The SF3 games have bee Street Fighter’s bookend for twenty years now. SF4 and 5’s lore has served as a great transition between SF2 and SF3, providing us with load of information, new characters, expanded lore, etc. But maybe Capcom would like to venture the lore past SF3.
If they do plan to have SF6 be right after SF5, then the legitamacy of Ed’s Neo-Shadaloo group would be validated. His group would be taken seriously, if they were the main key antagonists for the story of the game. I do believe that Neo-Shadaloo seems more like a flash-in-the-pan. Bison had the power, and resources to have his criminal empire last for years (dating up to SF Alpha, and even before). Neo Shadaloo will need some more time to develop as a global threat that could match its predecessor. Therefore, that’s why I think they would be better suited as a SF5 story extention, instead of a focus.
Also, I love and (85-90%) agree with your plot outline. I think, however, that the second story would focus on the building of Ed’s Neo-Shadaloo, with the clashing against Gill and the Illuminati slowly rising to power.
Plot line - Young Commander Ed leads his newly formed organization into a new direction. With public fear of the rise of another Shadaloo, Fighters (new and old) enlist their services to bring down this new threat before they become an unstopable force. But what is really at stake here? And exactly whom can you trust when no one knows who is pulling the strings? Deception, vengeance, lust, and justice all packed in this continuation of the Street Fighter V story.
Learning that Ryu was the one to finish off M. Bison for good, Ed seeks to kidnap Ryu and extract this power for himself. With the aid of his second in command Falke, Ryu’s abduction is the first step to total domination.
Falke, possibly more attracted to Ed than she wants to admit, willingly bends over backwards to ensure the success of Neo-Shadaloo (possibly leading to downfall?)
Sakura and Blanka join up with Sagat to help find Ryu and bring him back
Chun-Li, Guil, and Cammy are asked by Kolin to investigate and stop this new Shadaloo group before they become too powerful. (Group still trusts her due that she was in charge of Rashid’s group in ASF, but hesitant) But While Chun-Li is away, Urien and Kolin kidnap Li-Fen for Illuminati experiment.
Reformed criminal Cody runs for Mayor but fierce opposition comes in the form when a new political opponent G announces his candidacy
G actually is funded by the Illuminati, a step into spreading Illuminati influence to the world leaders
I think menat will either serve as a guide for the good guys, or will be a vessel of consciousness for Ed (menat tells him one thing, while Falke tells him another, leading to conflict)
Chun-Li becomes the one to “end the organization” (Neo-Shadaloo), thus fully accellerating the Illuminati’s plans into full gear.
Chun-Li, Cammy, Ryu, Guile, Sagat, Blanka, Sakura, Abigail, Zeku, Menat, Reformed Dolls,
Ed, Falke, G, Urien, Kolin, Illuminati, Neo-Shadaloo,
Ending - Cody is elected mayor and pardons the Abigail of his crimes for helping to save the world. G is arrested for conspiracy to commit treason, accepting bribes, embezzling, etc. But G was only a pawn in Gill’s master plan. Sagat and Ryu have another rematch. Chun-Li comes home to find Li-Fen has been kidnapped.
