Okay, we’re working on deductive reasoning here since we all want to know when we can sink our knife into the 4th season of Showtime’s Dexter.

So, season 3 of Dexter came out on DVD a mere month before Season 4 aired, so we think it’s safe to make the assumption that you should expect the release date of season 4 sometime in late summer 2010.  You can sign-up for an Amazon pre-order email alert if you wanna be fast in the loop.
