5. All Islands Are Fully Accessible?

Long term fans of GTA games will know that past titles have barred access to different islands until certain missions have been completed. Restricted access to "unlocked" islands would be explained by tropical storms, damage to the structure, and other rather too convenient excuses. However, in GTA V, there is the possibility of all islands being unlocked from the second we slip in the disc. This is a theory I have put together using information we already know. There will be three protagonists in the game, and Rockstar have said we will be able to take control of each of these characters at will. If we are controlling Franklin, for example, Trevor and Michael will be going about their business throughout Los Santos, and we will be able to encounter them on the streets or take control of them freely. Considering Los Santos is so huge, that would mean traversing great distances of the map in order to do so, meaning perhaps there won't be any restrictions as to which areas of the map we can explore.
