As November comes, we'll get to give Pokémon Go a rest and immerse ourselves in Pokémon Sun/Moon. Via Nintendo Everything we've been made aware that the pre-orders for the so-called Z-rings have started on German Amazon.
These rings are merely accessories that make sounds, vibrate and lights up whenever you use the designated Z-move from the game (see what Z-moves are in the trailer below). They are not adding content to the game as say Amiibo for example, instead of being toys-to-life they are more life-to-toys.
Here is the bulletpoints:
• Feel the thrill of battle as the POKÉMON Z-RING lights up, makes sounds, and vibrates!
• The type based attack icons on each Z-CRYSTAL become visible as they light up when inserted into Z-RING
• Z-RING features two ways to play: synchronized with the video game for 4D experience or in role play
• Video game synchronization allows the player to feel the full power of the Z-MOVE!
• Get different Z-CRYSTALS to unlock different colors, sounds and vibrations.; Two AAA batteries are required and included with the set
See a couple of pictures of the ring below the trailer.
