String quartet recordings
After Reznor made an appearance at the Bridge School Benefit in 2006, a member of the string quartet hired for the performance stated that the songs had been recorded with Reznor in the studio.
Wave Goodbye Tour footage
The majority of the final shows from this tour were filmed for some kind of release, though it was never stated if it would be a physical or online release. Videos of only two songs from those performances were uploaded to NIN's YouTube channel.  
Greatest Hits album
Upon NIN's release from Interscope Records in 2007, it was stated by Reznor that Interscope would be releasing a NIN greatest hits album.  This was referenced again when Hesitation Marks was released, because "Satellite" and "Everything" were originally written for the greatest hits album.
Zack de la Rocha solo album
After leaving Rage Against The Machine in 2000, de la Rocha began working on a solo album with Reznor in which 20 tracks were produced. However, de la Rocha was unhappy with the album and the project was abandoned. Reznor has stated that a release of the album is unlikely anytime soon.
12 Rounds third album
A follow-up to My Big Hero had involvement from Reznor, but due to the collapse of Nothing Records, the album was never released. The band eventually obtained the rights to the songs and released a few of them online in 2009.
The Woman In The Window score
In 2018, it was announced that Reznor and Atticus Ross would be doing the score for The Woman In The Window. The music was completed, but the film changed direction and the studio ended up using a different artist for the score music. Fans have sometimes speculated that the music may have become Ghosts V: Together/Ghosts VI: Locusts, but a quote from the film's director seems to indicate that the music was much heavier:
It was a lot more brutal in my original conception. Both aesthetically, with really fucking hard cuts and really violent music — Trent Reznor did an incredible score for it that was abrasive and hard-core — and in its depiction of Anna, Amy Adams’s character, who was far messier and kind of despicable in a lot of ways.
