AsIn April 2016, as far as I am aware, the Family Group Sheet view has not been reinstated on the New Ancestry. However, you can access a Family Group Sheet as before by using the following URL structure:
http://trees.ancestry.com/tree/TREE_ID/family/familygroup?fpid=PERSON_ID
You can find the TREE_ID and PERSON_ID by looking at the URL when you are on an individual's profile page.
There is no link to this page from the existing tree, so it is either a remnant of Old Ancestry that will be removed in the future, or a feature in the process of being added to the New Ancestry trees.
