Nah I agree. Even i thought this could be his awakening when it was first actually shown off in 1037. He temporarily transforms into it with Shuron Hakke.
But really
@Roo has given good arguments for it. Not that I'm against it, it's that my bias and hope for Kaido is that he puts up a decent fight against G5 and Luffy just isn't fighting the clock or his life-force, etc. This happened with Doflamingo, but it didn't happen with Katakuri. I just hope it goes the Katakuri route.
