ken's gameplay moves pretty much shows that his power is supreme compared to his regular mode. basically similar to riot of blood, tremendous powerup, while losing control. you can argue about gameplay mechs but they are still used to judge what the character can do a lot of the times.
W-R-O-N-G-! He was wielding the power of Orochi. If he was, Bison would of obviously identified this in their conversation scene. And Ken's Shinbu Messatsu shows his ties with Orochi with the signature Orochi Skull as well as his scene with Riot Of The Blood Iori (I think).
feats aren't everything people. if ken is having orochi power AND psycho power to add to his own fighting powers then ken is going to be one ugly mofo to deal with. besides Riot iori will wind up getting tired in a matter of seconds.
a focused fighter with that much skill.........i'll go with Ken on this one. regular iori vs regular ken is a massive stomp in iori's favor, but this one, no way R Iori is winning.
Though...as always I'd have to disagree and say that I do believe Ken can handle Regular Iori without much trouble. Riot of the Blood Iori is another story.
just kidding. look dude i'll say it as it is. by the way "blood and flames" post in teh videogames discussion section. you might want to check it out. an extensive and knowledgable discussion of the flames and bloodline issues. its kinda like the Jin uberness explanation i gave.
see ya. and no Iori will beat Ken relatively easily. the day ken can make the ground shake and people kneal with mere powerups! no exaggeration. all from Iori's display in his KoF2001 prologue. he made the ground shake and Seth crumble to his knees after he just breifly powered up. and as explained, Iori=godtier.
have fun reading all that. ken is cool, no doubt, but he aint beating Iori. not now. not ever.
