GTA V trailer released today

After what seems like years of toying from rockstar, GTA V first trailer was released today. It looks like it take place in Los Santos (i think that's what it's called) unless the do the whole san andreas thing again. It sounds like you going to be a normal criminal trying to make it, going back to the older GTA games. I wonder how many disc will be for the 360? Because I'm sure it will be too big for just one. Hope to get more trailers soon.
