Leaked cover art for Justice League‘s Blu-ray release may rule out the possibility of an alternate cut – for now.
As he mentions later on, a director’s cut Blu-ray of IT (another Warner Bros. release) will drop sometime later in 2018, even though the standard Blu-ray is due out in January.
The studio would be undermining their own efforts (and Whedon’s) if they were to drop an actual Snyder cut.
Justice League isn’t expected to hit the home video market until March of 2018, so Warner Bros. could still course correct if they so choose.
