Here are some of the new and updated flat rides I've spotted in the screenshots….

I think this is the "Fire Cracker" , the new Oriental theme for the enterprise.

All three of these rides are versions of the Snow Cups from RCT2, the one to the left being the Coffee Cups, below is the Diamond Ride (African themeing), the Italian Policeman Ride (European themed), and finally the the Faberge Eggs (it's Russian themed)

Here are two new cars for the submarine ride, The one to the left is the Hippo Ride (African themed), the one of the right is a whale.

Here is another example of a flat ride being themed, it is an Inverter Ship from RCT, but themed as a Junk. (Oriental Themed)

New look San Francisco Trams for the Tram Ride (American Themed)

The Flying Saucers… without the flying saucers, this is the Dragonhead ride (Oriental themed)

Here is a new train for the car ride, The Husky Ride.

The Fighting Kites, a themed version of the twist, one of the many Oriental themed rides

Here is the Out Rigger Ride (Australian Themed), a lot like the canoe ride, only different. (That's the Surfing Coaster in the fore ground)
