4. CJ?
CJ, unlike our friend from Grand Theft Auto IV, actually lived in San Andreas. Right on the corner of Grove Street. I half expected to see him with Lamar or Franklin near the start or somewhere throughout. Maybe he'll appear in a 'mission' on GTA V Online. Although, you must remember that Mr Carl Johnson will be 20 years older now (as San Andreas was set in 1992). A CJ introduction in an expansion pack or DLC would be absolutely awesome. If Rockstar have big expansion packs (like they did with IV) I wouldn't be surprised to maybe have him introduced. Unless GTA want to keep our memory of CJ with the San Andreas Game, then I see no reason why he can't be introduced.
