This was posted on the gta.net forums in the fake screen shots. Now, bottom left is the GTA III 3 islands, and a NYC type island, with a huge island for I would guess NJ. It's huge, from a SA standpoint, it's about 2 times bigger if I remb. It's a good fake screen, but I'm postive that this is possible or bigger for 4.
It's impressive to say the least.
As a side note, I read that article from the NYC online site, it says that gta games have the option to "sell porn to children" which is complete ****ing bs. I remb my gta games, and not once was that an option and never should be. That artice is the first shitty tactic from the press to bring down gta...
