There's going to be a Sonny 3 but Krin announced pretty recently that he's really not working too much on it. It's on the backburner for him until Sinjid is done.
(Even though 90% of his fans prefer Sonny over Sinjid but nothing to do except wait.)
until sonny 3 comes out any one have a game that is good or sort of like sonny1/sonny2 sadly i dont think any game is going to be as any one of the sonnys but what ever
