Love SOCOM, but I don't see it as a good fit either.
If Sony wants to get back into the SOCOM game, give a small, internal team a chance with a remaster or remake of SOCOM 1/2. They need to build from the ground up cause the series is at rock bottom. It would allow the new team to create something people love and give them a chance to interact with the community. Let them learn about the SOCOM people loved before making a new one.
Or just give me a remaster of S2 with online support (wouldn't mind CA in addition to S2 for both groups within the overall community) and tell us it's been a fun ride, but it's over.
