NotJabba: Pillars of Eternity is heavily inspired by the Infinity Engine games, but it's not DnD based. Torment: Numenera, as a sequel to Planescape: Torment, is presumably a DnD game though.
Torment: Tides of Numenera isn't a sequel to Planescape: Torment, but a "spiritual successor". I'll keep what made PsT an amazing game (story-driven, weird and unusual settings/characters, text-heavy, ...) as they explain in their "vision" document, but it'll neither be a D&D game, not in the Planescape settings. It'll use a different tabletop video game settings, Numenera (which is made by Monte Cook, one of the contributors of the old Planescape line at TSR).
That said, Torment looks like it'll be awesome, and I'm a proud backer of it. There is current
a stretch goal running and the current backing offers are only valid until the end of the month, so I advise anyone interested in such games to back it right now.
To get back to the main topic, I would indeed like more D&D based CRPGs, especially in the Infinity Engine style. Eternity and Torment both look very promising, but wouldn't do any harm to add a few D&D based ones too :)
