Assassin's Creed games have become somewhat of a certainty in recent times with every year bringing one, or even multiple additions to the series. As a result they have become less and less innovative over the years, not to mention a lot less polished with Ubisoft rushing to meet their yearly Assassin's Creed quota.
However, according to a rumor that originated on 4chan and got confirmed by Kotaku Ubisoft might be slowing down the tempo with big Assassin's Creed games in order to allow them more time for improvements and polish as the series reputation took a big hit from the mess that was Unity.
If the rumors can be believed the next Assassin's Creed game, titled Empire, will be set in Egypt and will most likely release in 2017 as Ubisoft is shifting to a slower release schedule for their main series in order to ensure quality and bring back customer trust in the series.
If this is true, and I really hope it is, I can see the Assassin's Creed games once again being something of great interest to people. As it stands, they've been selling the same game for the better part of a decade now and I find myself currently a lot more intrigued by the upcoming sidescroller Assassin's Creed Chronicles: India than I do for the main series.
The 2016 "hole" will most likely be filled with Watch Dogs 2 which was previously rumored to be set in San Francisco. Also worth mentioning is that the upcoming Assassin's Creed movie will be premiering this December so along with the two sidescrollers slated for 2016 you should be set with Assassin's Creed this year.
Let me just reiterate this once more, the majority of the information above is based on unconfirmed rumors and while all of it certainly sounds plausible I'd still take it with a couple of grains of salt because even if it was 100% true everything could change in the span of a year.
Once more information comes up I'll make sure to update you.
