I guess I could point some things this got "right", but honestly, there isn't alot.

>Sonic Rangers being the name of the game after SEGA leaked it themselves by accident. Eurogamer link

>Leak mentions an attack named "spincycle" where you run in a circle and any enemy inside it takes damage, Sonic performs an action similar to this.

>Leak mentions that Roger recorded new voicelines for this, and up to that point, we didn't know if he was to return, and as a little bonus, we know that a voiceactor can record some lines before being "let go", since Jason recorded some lines for Colors before being replaced.

>there is a mention of a "cyberspace" and in the teaser, Sonic appears to have some digital effects on him, like he is entering or leaving the place.

That's the best I got, not much and honestly, it could still be all a coincidence and it's fake, so there's that, have a nice day.

Have a nice Super Sonic!

Yeah, no, until we start seeing more footage, I'm not buying any of this. I'm gonna have to see some more evidence to back up claims like this.
