Are you still wondering about what could have happened with Star Wars Republic Commando 2? One of the original developers who made the game has actually answered this question.
LucasArts and EA dropped a huge cliffhanger in the end of Star Wars Republic Commando, when Delta Squad had to leave behind one of their best, Sev.
No less than Star Wars Republic Commando‘s lead developer, Brett Douville, explained what plans LucasArts were coming up with behind the scenes:
There were two competing stories that were being pitched, one being developed by Tim Longo and one by lead level designer Kevin Schmitt. In one, you would have played the side story of Revenge of the Sith and carried out Order 66, hunting down Jedi as a team. In the other, Sev would have been the first man in the Rebellion army — the tagline was something like, “Every Rebellion begins with a single soldier.
Tim’s plan would have had Sev start the Rebellion army, training a new generation of soldiers to fight the Empire: In my own imagining, I like to believe he’d go after his pod-brothers and counter-program them so they could fight the Empire together. I don’t recall what Kevin Schmitt’s would have entailed, but I like to imagine there would be a mission where you’d rescue him.
As for why they never followed through with making a sequel, Douville explained that they were never even able to make a formal pitch, due to the company undergoing a reboot. This was actually a major reorganization undertaken in 2004 by its new president, Jim Ward.
That reorganization proved to be a dire affair, cutting down the studio staff from 450 to 190. According to the book Rogue Leaders, Star Wars Republic Commando was one of a few projects fortunate to survive the said reorganization. Shortly after this reorganization, LucasArts released the first Star Wars Battlefront, and the first Lego Star Wars The Video Game a year later.
