Yeah, they said a "major" Assassin's Creed title is coming out next year, probably 3, because they've already come out and said that the next game will be the last game revolving around Desmond.

So really, I think it's entirely possible that we could have an Assassin's Creed game played mostly in modern times on the way. but then there's also a rumor going around that our next playable ancestor will be in Egypt. But who knows how accurate those rumors are.
