Seem quite legit, detailed roads and such.
Guessing the island off it is Santa Catalina Island (similar shape).
San Andreas map to compare:

I am with the 1st few comments in it looks a little small, as one of the comments i read is its bigger than all the sand box GTAs put together which would make it rather large and as per the SA map looks about the same if not bigger, the biggest city doesnt even look bigger than 1 of the islands in GTA 4

Having watched the trailers and stuff again to me this map does not match up, i could be wrong but atm i is calling bs on this leak

Ok maybe i stand corrected - having re looked at the GTA4 map (while playing) the big city may in fact be the same size more or less as all 3 islands combined! So i retract my 2 above comments and say this may well be legit!

They did specify it as interior and exterior when they said it was bigger than all 3 of Red Dead, IV and SA. Obviously referring to the underwater and, hopefully, a lot of interiors with buildings.

I know it could be, I just put it up because it could also be real, and if it's fake then someone has made a lot of effort to make it look legit.
