The listings for Unite for the Universe have been removes from Toys R Us Japan. The previously reported Japanese series that extends the Revenge of the Fallen line seems to be in limbo with one retailer Amazon Japan is still listing the items for sale with no notice of cancellation.
These releases are much anticipated for the Voyager class Optimus Prime with Jetfire combiner super-mode. Hopefully this is just TRU changing their listing and the will be out June 26, 2010 as expected.
