So while browsing the N4G news, I found an article that rumored that the Grand Theft Auto: V map can actually be the biggest Rockstar has ever designed. If this is true then that means that San Andreas could've gotten a whole new makeover (just like Liberty City) or maybe there are new cities in San Andreas.

Now there hasn't been much evidence if San Fierro and Las Venturas will be included in the next Grand Theft Auto installment. So far the only place that has been revealed is Los Santos. So that can also mean that Los Santos can be bigger than before, so it'll probably be more like the size of Los Angeles.

From the article:

Grand Theft Auto V heads to the city of Los Santos and surrounding hills, countryside and beaches in the largest and most ambitious game Rockstar has yet created...in a re-imagined, present-day Southern California

Mais c'est encore mieux quand on apprend de la bouche même de Sam Houser, le fondateur de Rockstar, que la surface de jeu sera près de 2 fois et demi plus grande que celle de Red Dead Redemption
It is even better when Sam Houser, Rockstar founder, says the map size will be almost 2.5 bigger than Red Dead Redemption.

Whatever the deal is with the map, I hope that it's big.
