It's unlikely Watchfire, the 2nd Village Selection, the 3rd spire selection, the 2nd SoK, the 2nd Rogue Hideout, the Deco Selection, the One Up, or the Tactician Tower upgrade got scrapped imo as they're either flavor for the event or staples that new cities may be chasing.
That leaves VT Upgrade(yawn), Hall of Fame(not offered every event), Gigantic Medals(yawn), Santa's Workshop (flavor, but so outdated by now that it'd be a public service not to offer it), Mass Self-Aid(yawn) for them to have picked 3 to scrap if you want to believe they'll offer all 3 cars one more time.
