This is not official but rockstar did say something about designing a new island for GTA 4.. Like i said its not official but it would be good for the GTA Lovers out there, And maybe if there making an island (Hopefully not too much) Then they might make a couple of cars or something.. But this new island (Unofficial Date) But they did say something about it being next year sometime
Sorry if you already new this.
