So (despite how frequently I've been wrong this year), I haven't heard anything about an "icon" for this year. That's a little bit odd, because I had heard about icons by March the last couple of years.
This artist character could be an icon, or it could be a character a house just focuses on (which is something we've seen a few times in the past). The Collector (Darkest Deal), Boris (Case Files), Sweets, the Barmys, the Siren (Dead Man's Pier), Evangeline Albright/Glowing Mother (Graveyard Games) were all characters central to their houses that, in any other year, could be leveraged as marketing icons and WEREN'T. So, just because a house features an important character, that doesn't mean an icon is imminent.
I would, legitimately, be surprised if Universal introduced an "Artist" icon the same year they have "Art the Clown."
