You sir are the most ignorant guy around here since the "Brawl should be on PS3" guy back in early summer.
And believe it or not, Sonic has the highest chance over ALL 3rd parties PERIOD. With Sonic's possibility of being in the next game, Sonic's future looks bright in my eyes. Sonic is not a"if you still play, then you need a life" character.
Future Sonic Games
Mario & Sonic at the Olympic Games: Will sell great even if it sucks eggs.
Sonic Rush Adventure: Original i heard was good, they couldn't mess up a sequeal could they?
Sonic RPG: Title still tentative, being developed by BIOWARE. Have they made a bad game yet?
Sonic Riders Zero Gravity: May be good depending how Sega can do to the controls. Most interesting, is how will it use the Wii's controls.
So just ignore this thread if you think this is spam. But don't be surprised if Sonic appears as an update on Smashbros.com.
