Krasnodar Krai and the area around Sochi could actually produce a decent race too, with hilly stages around Novorossiysk and Tuapse, and a mountaintop finish either at Mount Akhun or at Rosa Khutor or Laura, the mountaintop Olympic ski resorts.
Al-Ain is in Abu Dhabi and only really has the one major hill there, so I don't see that being the source as long as competition between the Emirates is a factor. They'll probably be building some rises on the slow gentle uphill inland or something for that 68km cycling circuit they're developing. Might have no "real" hills but be up and down all day, a bit like the Krylatskoye circuit in Moscow.
From the mooted event though, it seems like my apocalyptic vision of the future in the Race Design Thread simply wasn't apocalyptic enough. This truly is turning into F1, with the heads of the organisation openly siding with the ones that win the most often, more corner-cutting than the square circling society, and the sport selling out to the highest bidder thousands of miles from the fans or any local interest for a series of soulless events that provide next to no spectacle and little in the way of interest visually. This event will be like the equivalent of the Bahrain Grand Prix. One of the most dull circuits of the year, one of the most dull races, little to no overtaking possibilities, shorn of even the diversions of the champagne, in front of no fans, in baking heat. Sounds like the future for sure.
