possibly with it been back in San Andreas,
Ill be interested to see if you can go back to his home street from GTA SA and if theres any easter egg's or similar there.
There is one thing that worries me slightly with all the claims that this will be the biggest open world game to date,
A couple of the open world games that I've played recently (Darksiders II been the biggest culprit) have increased the map sizes dramatically but have not increased the amount of A.I/Challenges on the map proportionally resulting in alot of time just travelling.
On the one hand I think GTAV is probably not likely to suffer this with the choice of three story lines to follow and a main story line and probably countless side missions, but on the other the original San Andreas game did have this same problem for me in some places. GTAIV seemed to me to have a smaller map than GTASA but was alot fuller.
