It is nearing 3 years since gtaIV was released. Imho the first stages of devolpement for the next gta was started 6 months before IV was released.(just an assumption). I have no idea where the next location is, I wouldn't mind for any location however, as long as it has a somewhat diverse environment. I the the most likely place is Vice city. However, I prayed its not 80s again. SA is also possible but I don't think London will be done again. I wish GTAV would be more like Vice City, warm sandy beaches, 80's feeling and stuff. GTAIV is kinda "dark" and everything so it gives a feeling like a war is going on.
Anyway what do you think if it would be in San Andreas because there's alot of space to play in theres a beach, a country side, a "place to gamble", and a city, and there was also alot of things to do in San Andreas, and GTA San Andreas only had 1 story line, all the other games had multiple stories like Liberty city, and vice city.
Would you not like to see something different? Well I wouldn't mind a location similar to Liberty City, Chicago for example. people think Chicago Is similar to LC/NYC.
If Rockstar are going to do Chicago for GTA V location then they need to get It right. I thought LC needed to be more dangerous In places like Hove Beach. So If Chicago Is the location for GTA V then there has to be more dangerous neighborhoods.
