There is a new Scrubs series on the way. It takes place in a medical school and in the near future. Turk and Dr Cox are professors at the school. JD and Elliot are married and she is pregnant with their first child. The character of Dr Denise Mahoney that was introduced as an intern in the last season of Scrubs, will be the chief resident. Three new characters will be introduced, all med students.
Eliza Coupe, Donald Faison and John C McGinley are signed of permanently to the new show. Zach Braff and Sarah Chalke have signed on for six episodes, with maybe more later on. Judy Reyes, Ken Jenkins, and Neil Flynn have not been signed to join the new show. Filming as already begun, back in August I think (would have to go back and look at Zack Braff's Facebook page to be sure), but no air date is given as of yet.

Definitely go back and watch the show from the beginning. It is a definitely worth watching. It will make you laugh and make you cry, all in the same episode.
