Another big thanks to kei17 over in Japan for the Jump scan and translation/information. Let's just break it down clearly and quickly for you, since I'm pretty sure that we can all barely contain our excitement:
The DBZ TV series is receiving an extensive "refresh" for Japanese television airing
This is a celebration of the 20th anniversary of DBZ
- While based on the original animation production, it is being updated with new technology
- This includes extending the frames for formatting on an HD 16:9 display (note: not cropping the image)
- The original Japanese cast is re-grouping to re-voice the show (where available, and unfortunately not including those that have passed on, such as Hirotaka Suzuoki [Tenshinhan])
- Sound effects are being updated
- Unlike the general show, the OPs and EDs are being completely redone
- While not in the above announcement, other reports are noting that the number of episodes is being reduced from 291 to approximately 100
This begins 05 April 2009 @ 9 am

HOLY kitten I am looking forward to this. Most of the original voice cast is returning. No fillers and waiting 10 episodes for a fight to finish when they only have 5 minutes (lol Namek). The OP's and ED's are begin redone? HELLZ YES! And Oh my God its playing in HD? Goku going Super Saiyan? Gohan going Super Saiyan 2? *Droooooooooooooooooooooool*
April is going to be awesome. Seriously inner fanboy is about to explode. TOO EPIC FOR WORDS.
Stay tuned for "ON THE NEXT EPISODE OF DRAGON BALL Z" starting April 5th!
