no vice city was excacly 2x bigger (think about it before you say it)
well, i think that there are going to be several islands including vice city liberty city and san andreas. i think the map will problebly be at least 5-6 time bigger then san andreas. i also think there will be hurricanes/landslides/tornados/floods/snow/bullshit/and more bullshit.
thats what i think
