The series Star Trek: Discovery, due to be released in early 2017, will be the first new Star Trek series since Enterprise. According to Wikipedia:
Set to premiere on CBS in January 2017 before moving to All Access, the series will introduce new characters to the Star Trek franchise, and will not be related to the 2016 film Star Trek Beyond.
The same article mentions that it will take place in the original timeline.
Has there been any confirmation of what year the series is set in? Is it before or after Star Trek: Beyond?
