Probably not, every FO game as of yet has been set in the U.S and it will most likely stay that way. Though, there was a cancelled FO game that would have gone to both Europe and Asia.There were two planned fallout games, one in Europe right before the Great War and one where the BoS sends an expedition to China - both were scrapped in the very early stages. For now it seems unlikely.
I've always felt Europe would be mostly intact, or completly destroyed. But Asia just might be a squinty eyed wasteland.
J. E. Sawyer said that he wants to work on a "Fallout: Resource Wars" sometime and it would be in Europe, but would be in the 2060s so before the Great War.
