I believe they did a small short on Harry on FB back when he was pre-revealed, to tease the fact that he is around.
That said, they have seemingly distanced him from the Crypt TV branding, sooo I don't know what's on with Harry there.
Honestly though, I could buy him being the center-point. Afterall, he was the emphasis of the Eli Roth Tram back in 2016, and I doubt they would've put him in the Tram for 2018 just for craps and giggles.
