The fall TV season is barely underway, so can it be that we're really already looking forward to 2013?  If you're looking for fresh 'Shameless, ' 'House of Lies' and 'Californication,' absolutely!  Showtime has made its 2013 lineup official, kicking off with new adventures for the Gallaghers, Galweather & Stearn, and even Hank Moody, but which Sundays will be getting positively sinful with the network's new line-up?

Sure, there are little Showtime shows like 'Dexter' and 'Homeland' that will be back soon enough on September 30, but what of returning favorites 'Shameless,' 'House of Lies' and 'Californication?  The good news is that all three will be back on the same day, but the bad news is that we'll have to wait until Sunday, January 13.  And boy, are our Sundays filling up fast.

First up, 'Shameless' will debut its third year at 9:00 p.m. with Steve Jimmy (Justin Chatwin) moved into the Gallagher household, Fiona learning the ups and downs of having a G.E.D. while Frank finds himself in Mexico.  Next up, 'House of Lies' debuts his sophomore season dealing with the fallout of the merger disaster, while 'Californication' will close out the night at 10:30 p.m. with Hank Moody's novel being turned into a Broadway show.

And don't forget, the final season of 'Californication' will feature not one, but two 'LOST' alum in Maggie Grace's infamous groupie muse character (potentially to be spun-off), and Jorge Garcia.

What say you?  Are you excited to have your "Sinful Sundays" this January with 'Shameless,' 'House of Lies' and 'Californication?'  Which are you looking most forward to premiere?  Give us your predictions in the comments!
