Rumours are rife in suggesting that the next DLC coming to GTA 5 is going to introduce a casino in the game. The casino will come together with many new mini-games and also new heist missions.
Now, the rumours are claiming that the casino won’t be situated in Los Santos but at a separate location instead. The word is that the next DLC will add in a new town called Clifford City and it will be a replica of Las Vegas.
Unfortunately, details on this are still scarce at the moment so it is best to take the rumours with a grain of salt. We can expect Rockstar to shed more light on the subject when they announce on the next DLC for GTA 5 in the near future.
