I have received news that the next structure deck is scheduled for release in June. The deck is called the Tomb of the Divine Guardian which is an Earth and Rock monster deck based upon ancient Egypt.

There are also speculations that the holofoil card is an Exodia look-alike card called the Sphinx Exordo which has a defense of 4000. Also, the Shadow of Infinity Sneak Peek is in juts two days.
