At their Sonic panel at SXSW panel today, Sega confirmed that Sonic Mania, which launched last year on PS4, Xbox One, Nintendo Switch, and PC digitally, will be getting a digital release later this year. It will be called Sonic Mania Plus, and it will come with two new playable characters, a new game mode, an expanded four player competition mode, and special holographic packaging.
As for the two new characters, they will include Mighty the Armadillo and Ray the Flying Squirrel; all of this will result in the physical version of the game being more expensive than the digital one. Where the digital version was only $20, the physical one will cost $30 instead.
That said, if you got the digital version, you still get all the new features available to you at a reduced price as DLC- so there is that, at least. Meanwhile, the physical version of the game is set to launch this Summer. Sonic Mania is available on Nintendo Switch, Xbox One, PS4, and PC.
