It turns out the BIONICLE 2015 poster is actually the back cover of a 2015 BIONICLE catalog that shipped with the new LEGO Club Magazine. There are no digital copies of this catalog yet, but Voriks Forge has uploaded scans of this new catalog. You can also check out all of these pages below. Of notable interest, the Mask of Time is confirmed to be present in this universe.
Nice!:D but, on what page is the Mask of Time mentioned?
It’s on page 7, the one with the 6 golden Toa masks around the Mask of Creation.
