Episode IV became #1 of all time once it premiered, Episode one became #2, now Episode VII has become #3. At this rate, Episode X will probably be #4.
Regarding China, Rogue One has some chinese stars, and while i doubt it will be enough for the brand to reach Furious 7 and Transformers 4 heights there, it might give it enough of a boost to stand alongside Avengers 2. It will be interesting to see how much the market changes, right now Star Wars is the most powerful of all film franchises (unless Avatar 2 blows up like it's predecessor, which it probably will in China), but it's not so internationaly yet. That said, Furious 7 was a unique case, and while the Fast & Furious films will probably still make more than a Billion easily, they probably won't do as much as the 7th film did.
Anyone thinks 2 Billion for Episode VII is still a possibility? It only has to make around 20 million more in order to reach that number.
