When will the trailer of the warriors movie come out?

According to the warrior cats official website there are no warriors movies currently in production and no definite plans to make one, "whatever you read on the internet!". There have been discussions with various production companies but nothing has worked out so far. Erin Hunter said: "We'll wait until we can make a Warriors Blockbuster!

Also, there is no Warrior Cats movie on IMDB yet, so the movie, if there is one, will not be out for another 5 or more years. (http://www.imbd.com/)
