OK anyone saying it is New York City is stupid.
Yes it shows the Statue of Liberty
BUT IT'S LIBERTY CITY
No GTA has ever been modeled exactly after a real city, and this is the exact same case. Yes, it does look a lot like New York, but they aren't going to call it New York, because they don't want to have to make the whole city exactly as it is in New York. Also, If you look closely on the cop cars they say "LCPD"
But it isn't the Liberty from GTA 3, it will probably be amazingly HUGE, and there is no doubt in my mind they will have all the country side because that was the big claim to fame in San Andreas that made it different then the rest of the GTA's.
This trailer was dissapointing because it didn't actually show any real information on the game, it only showed the city and graphics and character. No weapons, only showed like 5 cars, and it was so short. But it still shows that they have gotten some stuff done on it, and from here, they will just keep releasing more information since it is close to being released.
