Does Hasbro have a "Top Secret" Postcard for SDCC?

An anonymous Seibertronian has sent us a very interesting message regarding the San Diego Comic Con. We currently have no way of proving this message though I'm speculating that this postcard will feature upcoming figures that haven't been revealed from either the Classics line or possibly the Movie. Here's what this Seibertronian had to say:

"Huge fan of your site. I visit often!!! I just wanted to let someone know that Hasbro will be handing out some sort of postcard at their panel at the San Diego Comic Con. What's interesting about this postcard is that they're keeping it TOP SECRET until the convention. Even the Comic Con doesn't know (yet)what it looks like/what image(s) it displays. Hasbro's being very touchy about this postcard though. They do not want anyone knowing what it looks like. I have a very solid source for this. I though you might want to pass the info on!!! It looks like there's something very exciting to look forward to at the Con!"

Make sure you keep checking SEIBERTRON.com for developing news and for further information about Hasbro's possible secret.

UPDATE: I just received some additional information from my source that this is NOT related to the movie which leads me to believe that this postcard will feature upcoming Classics Transformers figures that we haven't seen yet. Time will reveal all to those who are patient ...
