As long as it's not Drabbids ...
NEVER rabbids!
Justice League crossover would be cooler since he could get a race with Flash or Superman while in Avengers he would only be able to race with Quicksilver.
Ah! But the thing is... as a Sonic fan, I concede that the Flash is indeed faster than Sonic.
I mean, while Sonic has reach speeds surpassing sonic-speed, his speed is still limited to a few remaining laws of psychics that prevent him from doing too impossible things.
The Flash however, his superspeed comes from the "Speed Force" which makes all speedsters connected to this force an embodiment of speed. This allows him to run faster than light, to vibrate his molecules to be able to phase through matter, or cause matter of solid objects to be instable and explosive and of course time travel, at some point he needed some sort of cosmic treadmill to time travel, but he doesn't seem to need it any more, allowing him to run through time and reset the universe if needed.
Compared to Sonic, the Flash would just be too OP next to Sonic when it comes to speed and effectively make Sonic's presence kind of pointless.
While I haven't written a full fanfic over the idea of a Sonic and Justice League crossover, my premise in mind is that the Chaos Emeralds have scattered on DC-Earth. The presence of the Chaos Emeralds on this earth has caused
the seven forces of the universe to become instable and it's associates powers to be out of whack, thus nerfing the Flash's superspeed as well as many other superpowered heroes and villains giving Sonic and his friends more of a fair advantage on this Earth full of superheroes.

I'm hoping it will be "Chao Adventure 3", a mobile game that allows you to upload chao from a brand-new Sonic game that's potentially a remake of an old one.
Sonic X Shadow Generations Is Reportedly the Next Sonic Game

I kinda wanna call "bullshit" on it. Some fans think it will be a remaster of Sonic Generations when it's fine just the way it is.
Plus, since Sonic Generations, we only had Lost World, Forces and Frontiers. Why not wait six more games before releasing a sequel to Generations?
