So far, there aren't any DC films slated for release in 2014. This is odd, especially since Marvel and Sony will have 3 Marvel films released that year (Amazing Spider Man 2, and 2 Unrevealed films), so it seems DC won't be joining in the competition that year.
Why do I think so? Well, keep reading.
The reason I think there won't be any DC films in 2014 is because they've run out of characters. Now, I know what you're thinking: "What, are you kidding me? DC's got tons of characters they could use!". That's true, but they aren't using any of them in films. Let's take a look, shall we?
The Flash
Let's just take a look at how many times Flash has been 'moving along':

Look at the dates on these articles. Flash has been in development hell since freaking 2005. I highly doubt DC will suddenly become motivated enough to push for a Flash film now, especially with the critical and financial failure of Green Lantern.
Wonder Woman
Two words: Television Pilot. It's clear from that failed concept that it was going in the absolute wrong direction for the character. If a TV series couldn't get off the ground, I highly doubt WB will have enough confidence to go for a whole movie. Again, the failure of Green Lantern also hurts other DC characters. Not to mention DC hasn't exactly been pushing for a movie recently. They have in the past however.

Batman Reboot
Of course! Batman! DC's namesake and main moneymaker character! Certainly DC would never turn down the chance to make a Batman film, right?
Wrong. Mainly for the simple reason: it's simply way too soon. With The Dark Knight Rises having come out two years before 2014, a reboot would simply be stupid and too quick. If TDK took four years to get a sequel, there is no way they could reboot in only two. It's simply unwise and very highly unlikely.
Superman Sequel
Oh, but what about the famous Man of Steel himself? The buzz seems generally positive, and although the film doesn't come out for another two years, a sequel to Zack Snyder's film is certainly not out of the question. There's no reason to doubt a sequel, so why not have one of the world's first superheroes headline 2014 for DC?
Simple: Man of Steel comes out in 2013. One year after the film comes out. Schedule wise, the feat is impossible. Making a sequel one year after the original is impossible for a special-effects heavy film like Superman. They would have to film the movie while the first one is still in theaters, wrap it up in only a few months for enough time for the special effects. It's straight-up impossible.
Green Lantern Sequel
The film had massive negative reception and didn't make back it's cost. The studio only made about 100 million from it, with the rest going to the theaters. With a total cost of 200+ million, plus marketing, this film is almost definitely not getting a sequel anytime soon. If Superman Returns made 300+ mil and couldn't get a sequel, GL aint going anywhere fast.
Various Other DC Heroes
How could I have been so stupid! DC has a whole world full of characters to draw from! Blue Beetle, Booster Gold, Green Arrow, Black Canary! DC drawing from one of all these characters to make a film is almost certain, right?
...Right?
Sadly, no.
Look through the top of this list. Flash, Wonder Woman, Green Lantern? If they can't get those films to work properly, do you really, honestly think, any of their lower-tier heroes stand even a bit of a chance. Remember that Blue Beetle TV series? The one Geoff Johns made footage for and that there hasn't been a single whisper about since the footage was unveiled?
Yeah. That's what I thought.
