After reading all of this, I remember hearing a rumor about this maybe a year ago, thought it was some quack trying to get money. But if there's evidence of this, then well... let the courts decide. The Matrix is one of my favorite movies, and I never "worshipped the Wachowskis" or felt the need to remain loyal. The movie is great, and nothing really can change that.
However, if she says that the Wachowskis did Reloaded and Revolutions by themselves, perhaps that would shed more light upon why the sequels weren't as popular. 😛
