Ubisoft, in a rather sneaky way announced which games will be released this fiscal year. I say fiscal year as they announced Ubisoft announces Far Cry 5, The Crew 2 and new Assassins Creed.
In a presentation of a financial report. Well, that and Twitter. Other then the titles being announced there is no information on release dates and well, anything at all. For Far Cry 5 and The Crew 2 Ubisoft has been showing logos on twitter. Logic dictates that the games will be released somewhere starting now and 2018. You can expect some more details on E3 of course.
Ubisoft has not mentioned the new name for the new Assassins Creed. Earlier on it was already mentioned though that the Origins release will take place in an Egypt scenery, and in fact would be a prequel. In the twitter teaser they state "a New era begins".
