Time has run out for a new character to be introduced for the Glasses, I believe. It's possible that the Wheel is going to be left unexplained and not feature in the ending at all.

(I hope not, but there was a hint that the Wheel may not mean much in a recent podcast with Alex Hirsch, where he was asked about Wendy being the Ice Bag. "What kind of mystery show writer would I be if I answered...who or what that was, if it was anything? For all you guys know, it means nothing. For all you guys know this is just a fun little image that we snuck in...".)
