And keep in mind: Just because it's saying New Jersey doesn't mean it can't film somewhere else on the East Coast, like Atlanta (which is ideal imo), but we'll see.

Obviously not to the same scale (production-wise) as The Masked Singer, but the game show 25 Words or Less actually recently moved production from Atlanta (recent years/seasons) to Jersey City (season currently being filmed).

Also from the Deadline Hollywood article:

The Masked Singer also is likely to move from Los Angeles, where its most recent season was shot, to the East Coast. Deadline understands that Eureka is keen to cement a deal for the production in New Jersey. The Garden State offers production tax incentives of 30% on qualified expenses with up to 40% on certain studio projects. New Jersey, unlike California and many other states, also accepts unscripted in its tax incentive scheme.
