At least that's what we're being told over on KPopStarz.
However, the same article - by Miguel Abesamis ('Death Note' Hollywood Remake Gets A Director; Adaptation Slated For An April 14, 2017 Release (August 18th 2015)) - also quotes Warner Bros stating that no release date has yet been decided.
Moreover, Abesamis's stated source (The American Adaptation of Death Note Has Its Director, IGN, April 28th 2015) doesn't mention a date at all.
I guess it's more of the 'wait and see what rumour comes next' ethos, in which we Death Note fans are very well versed.
What each report (and all my latest information besides) has in common is that Adam Wingard is most definitely still poised to sit in the director's chair. What Abesamis additionally adds to the general slush of gossip is that Wingard will switch to Death Note after he's finished with The Woods.
That does not bring us to an actual date though.
I suspect that whichever editor produced the headline misread something fundamental. Abesamis's article also discusses a Hollywood adaptation of Ghost in the Shell, which - one of his previous reports tells us - is due for release on April 14th 2017.
Or maybe none of them are coming then. He just likes the date.
