Rumor: Death Star Transforming Vader? has posted an interesting article regarding future toys.  It is unclear as to whether this article refers to a visit by the author to a Toy Preview or if this is just a fictional 'wishlist' type of story.  Here is the paragraph in question…

"Oh, funny thing, as the team left the toy aisle of the future, our man Chris tripped over a Death Star Transformer that someone left carelessly on the floor. We all kind of laughed, which now looking back to the future we can rationalize that that was mean and insensitive. Thankfully Chris wasn't hurt (except for a bump on the head), but he did point out that it transforms into a big Darth Vader figure."
