Finally, been waiting for this for ages!
Hope they do it in the order they started, so Vice City then San Andreas afterwards.
There's been loads of speculation of SA but it could be anywhere really. A few Rockstar guys were spotted taking photos in LA but they looked like holiday photos so god knows.
Edit: Just seen this as well. The V is in the exact same text as the V on an american five dollar note.
First half of the V is stretched out, then other half is skinny.
