Late last year subscription company Eaglemoss ran a limited two-issue trial for a "Build the Ghostbusters Ectomobile" collectable self-assembled model in the United Kingdom.
The company has now updated their American website to include a countdown clock, indicating that the monthly installments will become available from around the 1st of January, 2020.
The countdown page also includes a waitlist sign up, allowing fans to be notified when the collection becomes available.
There's no word yet if the collection will receive a full release in the United Kingdom following the initial trial-run. This story will be updated as soon as more information becomes available.
