So I sort of signed up just to say this but, that 'red thing' you speculate on the bridge that you call a cue-ball. Resembles a red jinrikisha turned away from you to me.
Can't be a bike, there are two pixels for feet
I think the idea of a jinrikisha seen from behind, or rickshaw as it's otherwise known as (
http://en.wikipedia.org/wiki/Rickshaw), seems very accurate to the 'red thing', to me.
In the blown up image, the 'feet' are actually 2 wheels, much like a rickshaw. The black lines coming up from the sides are the poles that the navigator holds.
The light-coloured top would just be a straw hat, with the red part is the carriage for a person to ride in.
However, i could be wrong, and it could be anything anyone suggests at the moment. A gameplay clip in the next month would be very welcomed to confirm any of our suspicions.
If the region is based on Chuugoku, the big city could really be Hiroshima, as it's surrounded with water, just like Hiroshima has the sea and several rivers passing through it, forming islands.
I certainly agree with this. And on the left, as 4th KIRA mentioned, does look like a port or pier, which Hiroshima also has.
The city behind the bridge would possibly be based on Okayama as it has the Great Seto Bridge
Based on the Chuugoku theory, IF they ever have a desert in this region, it should be near Tottori (

That should be enough for speculation. Just need to wait now...
