Spyro Reignited Trilogy, a collection of the first three Spyro games coming to PS4 and Xbox One later this year, was initially due to release worldwide on September 21st 2018. This was somewhat significant, as a September release would have had it releasing twenty years to the month after the original Spyro the Dragon's North American release date.
It seems however, trying to release it in September to match up with those dates may have been a little over ambitious, because the game's release is now being delayed by two months, just a month out from when it was due to release originally.
According to a statement from developer Toys for Bob on the official Activision blog, the release has been pushed back by approximately two months, to November 13th 2018.
Everyone here at Toys for Bob is so proud to be reigniting the original Spyro trilogy after all these years. We’re deeply committed to getting these games right, so we’ve decided to move the release date of Spyro Reignited Trilogy to November 13, 2018.
I really hoped that you would be rescuing dragons and scorching Rhynocs sooner, but the Trilogy needs more love and care. In November when you’re exploring the Dragon Realms, Avalar and the Forgotten Worlds, we know you’ll agree the extra time was worth the wait.
While no official reason was given for the delay, many online have guessed that it might be connected to a recent story that only the first of the three games would be complete in time to be playable offline from the disc at launch, and that the other two games would require online downloads to be playable. Response to this news was negative, and it's possible this delay may mean that the other titles are playable on disc without needing updates. This is speculation, but it seems to be the internet's best guess about the delay at this time.
