I agree. It's a Ravenloft thing.Based on prior years, I think they will begin talking about it after Dragon Delves drops. They usually talk about books about 3 or 4 months in advance.
Dollars to donuts it is a Ravenloft supplement, similar to how Fprge of the Srtificer supplements Rising from the Last War.
The Venger thing mentioned in the OP has come and gone in the form of in-store play.
Without Kenreck, it's possible that their promotional stuff will be a little later than usual, but I agree with @Parmandur that we will probably hear about it after the mext book drops.
