You can state your opinion without using caps lock, you know.

It's a plausible theory. What we know, is that Ichigo's Quincy powers manifested as Yhwach from 1000 years ago, suppressed the real Zangetsu, Hollow Ichigo, and the Shinigami-power Ichigo have been using this whole time, was only the fraction of Zangetsu that his Quincy powers couldn't seal. There's no telling yet how the "fake" Zangetsu blade was created or what it was, but the important thing now is that Ichigo has a "real" Zangetsu.
