If you look at the latest games they've produced, I'm not really hopeful: Sonic Frontiers is an open world with assets placed all over the map without any harmony, giving you the impression of playing a game in alpha beta testing . Sonic's horrible 3D controls lack precision and Shadows x Generations is a DLC sold at the price of a full game because they included it with a game produced years ago , they also recycled a lot of levels from other Sonic game franchises and rhythm is butchered with 3d and 2d phases.
The last good game is Sonic Mania and that was designed by an independent team, only fan games offer a really good gaming experience. The truth is that Sonic's velocity and gameplay are uniquely suited to 2D, otherwise it turns into an ADHD game.
