I think @HamzaTR is more talking about “wishes”. What I meant is a higher probability of appearance, from the perspective of developers wanting to bring cities with seasonal changes.
However, they could make conditional Istanbul or Kyoto, but at the same time make a full winter in them - it’s a game, there are no obstacles to this 
By the way, there was a very good hint (BUT THE INFORMATION IS OUTDATED, SO THE PLANS HAVE LIKELY CHANGED), about what the next city will most likely be. This is from observations by @GDfromRivendell. It was supposed to be something from latitudes where lavender grows. Currently, France is the main hub for it, so it’s quite likely that a reference to these places was planned. Personally, I would be delighted! “Voir Paris et mourir”, as they say 
Although lavender can be alpine, of course, but we’re unlikely to get that.
