The movie just keeps on turning up with new surprises.
What appears to be a new Blue-Eyes monster can be seen at the very end of the linked commerical for The Dark Side of Dimensions, in addition to a small shot of a level 3 Houkai monster that Aigami uses half-way through the trailer.
Also, it appears that Aigami’s duel disk is comprised of a number of those cubes he’s seen holding in previous trailers.
Credit goes to Yami_no_Yami of GX_ST, aaaand anybody who managed to catch the commercial on TV in Japan.
Also, for those who are interested, the Shonen Jump issue with the first half of the two-shot prologue to DSOD has been out in Japan for a few days now, and it depicts some of the details for the new VR Solid Vision system that we see in the movie.
