In Anville town, there's a strange train and a man speaks about it, like said Silktree.
"This train car is the kind that ran a long time ago. Compared to contemporary cars, it has more parts, so I heard it was difficult to build. The old cars built with lots of small parts have their own unique beauty and attract a lot of fans. Those cars no longer run in the Battle Subway, but I hear they're still used in a faraway region. Ah... I'd love to be on that train! ".
Doesn't this train remind you something ?
Oh wait, the Cable car from Sanfrancisco.
What do Wikipedia say about these Cable Car ? "The best known existing cable car system is the San Francisco cable car system in the city of San Francisco, California. San Francisco's cable cars constitute the oldest and largest such system in permanent operation..."Y
Yes guys, i'm now 100% sure that we'll get Sanfrancisco.
Sanfrancisco has the famous Golden GAte Bridge loved by a certain Junichi Masuda (photos on his blog...)
Sanfrancisco-Unova can be like Johto-Kanto...
Sanfrancisco also has Alcatraz... perfect if we want to see again Plasma Sage...or Looker.
N may fly here after Black beat him...
Also around the "Golden Gate Bridge", there's a large ocean so, many dive spots area for a Pokemon Game. This is why Dive is in BW.
100% sure about this, and please, if we'd get 16 gyms, please a DARK GYM.
