Is SEGA actually involved in the Sonic the Hedgehog movie?

Well here's a bit of an odd one. We know that SEGA is tied to the upcoming Sonic the Hedgehog movie because Sonic is their character, but how much actual input on the film do they have? According to Crush 40's Johnny Gioeli, SEGA has absolutely nothing to do with it. He stated that as fact at a TooManyGames panel, which lead many fans to worry that the film would have the same fate as the original Super Mario Bros. movie.

Sonic Team's Takashi Izuka fired back after this statement was made, saying that he's a supervisor on the movie. That's all well and good, but is that supervisor in title only, or can he step in and make suggestions?

One thing's for sure. This movie is going to be extremely interesting no matter what the case is. All this debating about SEGA's input makes me want to see it more!
