FanPro has stated that they plan on Shadowrun being less North American centered in the future.
I'm thinking that they are going to go with London and Lisbon, with the other two being drawn from Constantinople, Vladivostok, Tokyo, Berlin, and Metropole.
Out of those five, Metropole, Tokyo, and Vladivostok are recently described (as of 2064 in SoA and SoLA), so make of that what you will. It is said that these books will be more like New Seattle in detail, if not format. We'll see.
