Now ITV and PBS have released more Season 4 pictures (past the one of Lady Mary they teased us with months ago). Above, Mary and Branson are together with their children in the wake of their respective spouses' passings.

Below, Branson and adorable baby Sybil are seen outside the estate. Click here to see all the Season 4 pictures so far.

"Downton Abbey" premieres in September in the United Kingdom and Jan. 5, 2014 in the United States. Who's getting excited?
