Honestly, that's pretty much the one thing that has me convinced that Crash is gonna be in FP2 at this point, ideally as the next fighter. For one, pretty much EVERYTHING about it thus far has been true. For another, Nintendo seems to hold Crash in high regard, calling him a gaming icon on several occasions, too!
