Sega Republic is an indoor entertainment centre being developed at Dubai Mall, the largest mall in the world.
They will have a spinning coaster and a drop tower amongst lots of other attractions. This is based on Sega Joypolis in Tokyo.
I am told the coaster is on site. I will hopefully get a backstage tour of the site on Sunday so can update then.
In the meantime here are the photos I have so far.
