SNEAK PREVIEW: NBC is providing sneak previews of this new prime-time series, based on games played on Ellen DeGeneres’ daytime show, this month, even though it doesn’t premiere officially until next year – specifically, on January 2. This series has a lot going for it, starting with the fact that, for this limited-run series, DeGeneres herself serves as host. But if it hits big and keeps going, can she keep it up while still doing her daytime show?
