Well, this is another one of those "maybe I'm paranoid" moments I go through, but I've been thinking about this for some time now.
My theory is this: the Sonic Generations page here on the site stated that Blaze the Cat will appear on the upcoming game, co-op-only or not, I'm not sure. However, I made a theory for the possibility of having Blaze appearing in the game as part of the main plot. Sonic Generations will be about time-travel, right? And we all know Crisis City will be in the game, thanks to the trailer, therefore, the events of Sonic 2006 will be revisited.
Now let it sink in for a while... See where I'm getting at? If Sonic Generations will revisit the events of Sonic 2006 and Blaze has been confirmed to be in the game, could it be that her sacrifice or her role will be changed somehow, or will Sonic and/or Silver be actually able to prevent it?
I don't know, maybe I'm getting paranoid again, but I really needed to see what do you guys think of this. How about it? Will SEGA put Blaze back into the main canon? Are they thinking of this possibility?? What do you think?
