They already confirmed that they created a full Elder Scrolls set, but they are waiting for the release of TES6
Outside of that, Idk what UBs they will push. Avatar made sense since no way a cooperation with Nickelodeon would end on just a Spongebob Secret Lair
They collaborated with Sega on the Sonic and Miku Secret Lairs, so probably one of the UB sets will be one of their other franchises, but I have absolutely no idea what or how it could work.
