What's NEXT for 3D Sonic? (An Analysis)

Now that Mania and Forces have released, and one game did a lot better than the other, where could Sonic Team be taking the franchise next in terms of its main line 3D entries?
One thing I realised after wrapping up with this video is I didn't really address whether or not I think a new 3D game will be coming out in 2018. Personally, I don't think we'll be seeing another main 3D Sonic game until 2019 at least, but you never know, we might at least get some spin-off next year for the sake of it.
