This is becoming another repetitive and annoying question, so I'm going to answer it on the FAQ board.

Edit 2: Ordinal Scale movie included an after-credit scene that teased the 4th main arc. No official announcement or word on the anime studio working on the project, let alone when it would be released, yet though.

Edit: A movie has been announced for a 2017 release (see here). It's highly unlikely that there will be any word on a new anime season until after the movie is released.

There are no news about season 3 so far. That includes both whether a season 3 will be made at all, and when the season is going to air if it does get produced. The only thing that is known is that the director of the anime does not want to start work on an arc that is not yet completed. Thus, unless the anime studio chooses a new director or convinces the current director to change his mind, it might take a couple of years for the anime to get another season.
