The upcoming DragonBall anime series "DragonBall Super" has been given a small teaser trailer.
The most we can gather from this short video are the animation quality (which is similar to new age stuff we've seen in Battle of Gods and Resurrection 'F') and the appearance of several characters (Goku, Gohan, Goten, Videl, Hercule, Vegeta, Trunks, Piccolo, Mr. Buu, Beerus, Whis, etc).
There might not be much to go off of but I can assure you the excitement is only increasing.
