Any clues in the DC Nation 2012 teaser ???

We are not going to draw conclusions too quickly, but this teaser from the American channel Cartoon Network presenting the DC programs which will be broadcast in 2012 contains some astonishing images.

We discover among other things some images from the animated series Batman, Green Lantern, Teen Titans and Young Justice.

But at the heart of this teaser, a few seconds are more important than others, and here they are on the screenshots below ...
The part of the teaser featuring the short films that will be released features what appears to be a LEGO Batman cartoon. We see Batman piloting a Batboat that is nothing like the one in the set 7780 The Batboat: Hunt for Killer Croc released in 2006. We also see what appears to be the Joker's Scuba Jet, and we discover a little further the Joker himself armed with a rocket launcher.

The Batman minifigure appears to be the one that will be delivered in the set 6860 Batcave.

The Batboat, if that's what it is here, as I'm hesitant with the Batwing itself, is a lot different than the one already released. At the front we find the same yellow marks as the one that can be seen on the Batwing of the set 6863. The Joker's Scuba Jet clearly displays the colors of the helicopter of the set 6863 Batman vs. The Joker and the Joker logo on the front.

The Joker minifig is the one planned for 2012 in the set 6863 Batman vs. The Joker, and which could be provided in a second set featuring Batman and his Batboat against the Joker and his Scuba jet ....

 So, can we draw any conclusions from these images?
Probably not by hoping for a set bringing together Batman and the Joker with their respective machines, but we will be entitled to these minifigs and these machines during the second DC wave. I put my hand to cut ...
