Soundwave84 over at TFW2005 has found the first listings for Transformers: Revenge of the Fallen related merchandise over at Amazon.com's Canadian site.  Among the list are the usual childrens books and junior novelization, but several items stand out of particular note.  Among the listings are 'Transformers Revenge of the Fallen 32c Mix Flr'  and 'Transformers Revenge of the Fallen 4/29/09 32c Mix Flr', which appear to be listings for book displays.  Also of note is what is likely to be the first Revenge of the Fallen tie in novel, 'Gatefold'.  Most of these have a release date of May 6, 2009.
