That appears to be the case, although the Pioneer Animation
site will not corroborate the story (yet)
From what I've heard, the munged dub will be released
under the name Cardcaptors, while the original will be
released without a dub track under the original CCS title.

I'm glad Pioneer is handling the original release.  After
seeing how some of their other titles have turned out
(Battle Athletes, Trigun, Sol Bianca) I couldn't help but
drool over the announcement.

Even though I can't stand to watch Sailor Moon, I couldn't
help but shudder when I heard how DIC'd over the show was...
I'm happy that Nelvana had the balls to try something like this.  Can't wait 'til the Sept. release....
