I myself have played all of the main series of Assassin's Creed, I love the little touches of history that Ubisoft includes in their games. The games are not meant to be historically accurate, but they are enjoyable to play and always come with an interesting storyline.
Assassin's Creed Unity was released in late 2014 and Rogue shortly before it. Furthermore, Assassin's Creed Victory was announced. It is not confirmed if that is the actual title or if that is just a code name for the next release.
Assassin's Creed Victory is rumoured to be set in England during the Victorian Era. Will this be connected to Haytham Kenway? Not much is revealed, however during the E3 conference we will get a glimpse at the gameplay. This will be the 9th game of the main series. It is the 8th game if you do not count Rogue as part of the main story line.
There have been countless locations that the franchise has reached, from Ancient Rome to North America. We have even been in the Caribbean as a pirate. As Ezio we have even been to Istanbul. Would it not be amazing if Ubisoft created an Ancient China universe in the Assassin's Creed franchise?
A game in Ancient China or Ancient Asia would be interesting and engaging. The architecture of the time, the weaponry that would be available would be creative and new. On the Assassin's Creed wiki there is history for the assassins in China. Lead by Fang Xiaoru in the 15th century. Ubisoft could easily come up with a story line or even use the one that is outlined in the wiki. If they do decide to produce a game in Ancient China that could open up so many different pathways. A game in Ancient Japan or Korea, and possibly Mongolia with a cameo of Genghis Khan.
In Ancient Japan or China they could also include many famous Chinese or Japanese people. Such as Sun Tzu, or Ubisoft could have the Templars supporting different clans and families in China while each Dynasty thrives and is toppled. The Ancient China universe is so expansive I really hope they make this.

Go ahead and read all about it for yourself. It may be fictional, but it is imaginative. If you have not played the franchise yet, I would strongly recommend it.

To end on a little teaser, what if they made an Assassin's Creed game based in Ancient Egypt. Now what would be something as well.
