Last May Sega announced Sonic Origins, which is a collection including Sonic the Hedgehog 1, 2, 3, CD, & Knuckles. Very little was revealed about these games besides they will be “native ports” and will release before Sonic Frontiers.
Since then there hasn’t been any news on Sonic Origins, until Twitter user Pan-hime noticed a Korean rating for it. Shortly after Sonic Stadium found new key art for the upcoming title.
Unfortunately, no word on when Sonic Origins will release, but it is interesting the key art went with designs from Sonic CD. Most notably Amy Rose, who was changed drastically following its release.
