Sonic Adventure 2 is definately canon but it's content in verses mode is not. Not including character boss battles either which uses verses abilities as well.

In Action Races in SA2B, Shadow is able to use Chaos Control with 60 rings and Sonic can use Sonic Wind with 40 rings. Knuckles and Rouge also have various abilities as well they can use with rings. Given the nature of these races and battles (such as a conveniant layer of snow down the streets of Downtown Race.) have little meaning to the story, they're regarded as non-canon.

Personally, I like the idea of "Sonic Wind" returning but only as the name for the various cyclone and whirlwind skills Sonic can do. Such as Blue Tornado from Sonic Heroes.
