According to Kotaku UK - which has consulted sources close to the project - we'll be getting a Spyro the Dragon Trilogy Remaster this year similar in scope to the wildly-successful Crash Bandicoot N. Sane Trilogy.
The games included will be Spyro the Dragon, Ripto's Rage!, and Year of the Dragon, and there's a chance that new content will make the cut. As with Crash, the package will boast vastly improved visuals and enhanced gameplay mechanics, such as a new save system. Vicarious Visions is handling the work, the same studio which produced the Crash remaster.
The trilogy will apparently be announced for PlayStation 4 in March this year, with a Q3 release. In 2019 it will then come to other consoles when Sony's exclusivity period ends. Given that Crash is rumoured to be coming to Switch, one would hope that this (unconfirmed) package will also make the leap.
