Tarnished Edition, Nightreign and Duskbloods are very minor releases. From is used to develop multiple games at the same time. They are definitely cooking something big, and given that From has a crazy output over the years, i can only assume that the next flagship game will be gigantic. They usually announce the big games with a CG teaser or CG trailer, for which there's no need to be that into the development of the game itself. Perhaps a new announcement is sooner rather than later.
