I don't know if this is what the OP meant, but I would personally like it know the answer anyway:
Will the conversion kit/app incorporate 1st ed. expansion components into 2nd ed. gameplay?
To put it clearly: Will the conversion kit/App included in the second edition only incorporate monsters/investigators/tiles from the 1st edition BASE GAME or will it also allow the use of monsters/investigators/tiles from EXPANSIONS (e.g. Call of the Wild) as well?
It will use CotW and FA as well. You can tell by the number of investigators included in the upgrade kit.
