It seemed as though you were trying to equate the two though, saying both are only missing 3-4 main markets that first weekend. Furious 7 was ONLY missing 3-4 markets, even if two of them were large. Age of Ultron might only have a couple large markets left to launch in (China, Mexico, Japan if they feel like showing up), but cumulatively those other 30+ markets are going to be a lot bigger for age of Ultron than Russia and Japan were for Furious 7.
Japan is barely a major market for most hollywood films these days. Furious 7 is going to end with like $20M there. That's not significantly higher than the film's take in Malaysia.
