GTA V's Map Leaked!!

Less then a week after the release of the first trailer, a photo was posted online and there are people saying that it is the GTA V's Map. The person who posted it on Twitter call himself as a former Rockstar employee who just resigned.

 

I don't know if it is real or not but here it is. If you want to see what else he said after posting the photo, his twitter account is TorontoJack233.

What do you think? Is it real or not?
