It doesn't mean that No Man's Sky won't be there though. Perhaps it's now in playable form and is going to be on the show floor.
I doubt it
For 2016 Exclusive Releases, I feel this will happen:
January: Witness
Febuary: Gravity Rush Remastered (US/EU), Day of the Tentacle Remastered
March: Uncharted 4
April: Street Fighter 5, Rime, Neptuina Victory II
May: Ratchet & Clank, HD Remaster (God of War Assention with God of War 4 Beta?)
June: Dragon Quest Builders, Heavy Ran & Beyond Two Souls Remastered
July: Dreams (Beta or Retail Release), HD Remaster (Puppeteer maybe?)
August: GT7 Beta, No Mans Sky
September: Dragon Quest Heroes 2, QD's New IP, Gravity Rush 2
October: FFXV, Last Guardian
November: Neir 2, Horizon Zero Dawn, Dreams (Retail Release)
December: GT7 (Retail Release), Kingdom Hearts 2.8 HD, Dragon Quest XI Western Release (or pushed to Jan/Feb of 2017)
Looking at past releases, FFXV will be a december game. And Dragon Quest XI prob wont come out in 2016 in the west, especially with FFXV release. Also
WHERE IS PERSONA 5 THERE?
