Valve is supposedly working on a way to make sure that season pass buyers get the content that's promised to them.
Dataminer and SteamDB (database) creator Pavel Djundik recently claimed that "Steam is working on a season pass survey for developers" that will only be "internal" to the digital storefront and kept hidden from everyday customers. The survey will apparently let Steam "track commitments of the high level deliverable and their dates to verify that [customers] received the content promised."
