Here's what I predict:
I already know about Sonic Dash, a new iOS endless runner starring Sonic the hedgehog and friends,
Sonic Jump add-on content (Mechanical Zone; Shadow, Vector, Cream)
And the next Sonic 3D platformer (Sonic Adventure 3?
)
I also predict Sonic 4 Episode III, a new handheld Sonic title (most likely a handheld version of the next mainstream Sonic game), and a new re release (Sonic Heroes or Knuckles Chaotix possibly), and possibly a new Sonic compilation (collection of classic games like Sonic 1, 2, 3 & K, CD, etc.).
Those are my predictions. This is not a Sonic game ideas thread, but I do have a thread for that.

Anyways, this is just a predictments thread for what you think Sega will have to offer for Sonic fans this year. Personally I think this year will be a big year for Sonic because last year Sonic didn't have very many games. Please post your predictments below! 
EDIT I said predicaments instead of predictments.
I fixed it though.
