Dexter Season 4 - Family Man vs. Trinity Killer?

It would be really nice during this long, dry summertime spell for television if the Dexter people would release another promo photo. Loved the first one, and am anxious for a second. I think it makes business sense because it won't get lost in a flood of other series' promotions and therefore would get more exposure and buzz. 

On second thought, I'm wondering too if the promotional depts. are cutting back on how much money they can sink into pushing a series? "Dexter" is still on pretty solid footing so perhaps promotional budget dollars are being spent elsewhere? As a from Day One Dex fan, I'm ready to start talking Season 4 now. Showtime, are you listening?

What can you tell us about next season of Dexter and this Trinity Killer played by John Lithgow?
Dexter star Jennifer Carpenter, who of course plays Dexter's sister Deb Morgan (and who is Michael C. Hall's real-life wife) just told us, "John Lithgow is a teddy bear. I think that's part of the fun of the story—how well do you know people you spend time with? It's about how we judge people so quickly and don't really know what they're capable of." Kristen
