Cassandra Clare shared this info:
Hey guys it’s Lily. I’m so excited to tell you that we’re going to be in Anaheim California for this year’s Wondercon where you will get an exclusive sneak peek of The Mortal Instruments and you’ll get to see our new trailer and poster. I hope to see you there. So 1) yes, Lily, Jamie, Harald, me, and perhaps others :) will be at Wondercon in Anaheim this year, doing a panel, answering questions, and most of all — debuting the new theatrical trailer and the new poster that will go up in theaters! 2) While it would be absolutely awesome if you could attend Wondercon to see us, if you don’t: this is still very good news since what it means is that there will be a new theatrical trailer and a new poster ready to go out into the world at the end of March. Wondercon is just a way of saying “THESE ARE READY TO GO!” (And trust me when I find out exactly when our Wondercon panel is and which movie the trailer will be attached to, I will post about it RIGHT HERE. I have been asking myself almost every day.) 3) Wondercon website: http://www.comic-con.org/wca
Cassie also took the time to post the following as a response to Lily’s video on Facebook:
Hey guys: I rarely post here, but do keep in mind that while the trailer and poster will debut at Wondercon (which is very normal for movies, debuting trailers etc at Wondercon/Comicon) the point is that this means that there will be a new trailer, which will go out into theaters, as of end of March, and a new poster, which will also go out into theaters, at the same time. No one releases posters/trailers just at a convention and no where else since as you say, most people can’t attend. It is a way of announcing that the trailer/poster is ready to go.
Stay tuned as more details are announced, including the date and time of the Mortal Instruments panel.
Any Shadowhunters planning on heading to WonderCon?
