We’re barely into the summer TV season, and ABC already has started shaping up its fall schedule.

Mind you, these dates are subject to change depending on what other networks do and the kind of buzz the new series end up getting. But at least we know when our favorites will be back. Among the highlights: “Dancing with the Stars” returns Monday, Sept. 21.  “Grey’s Anatomy” will be back, presumably Gizzie-less, on Sept. 24. “Desperate Housewives” fans find out who Mike Delfino married on Sept. 27.

“Ugly Betty” returns a bit later and on a new night,  Fridays,  starting October 9.

A reminder to “Lost” fans — the final leg of the journey starts in midseason (probably January) and runs straight through with no repeats.

Keep reading for the schedule. All times are ET/PT.
