MangaBlog has gotten in touch with TOKYOPOP Marketing Director Marco Pavia with regards to yesterday's reported cancellations of several volumes from the manga publisher. The main thing you need to know is that while these items are currently cancelled with Diamond, it does not mean that the series are being completely discontinued.
Initial D Vol 33
Basically this is part of the process of TOKYOPOP pacing its releases. That said, the .hack//SIGN novel special edition might wind up cancelled due to licensing issues-- but even that's not confirmed at this point. So don't worry, ARIA and Initial D fans, you'll still get your books...eventually. Most likely.
