Probably the most shocking bit of news is that the episodes have been edited down to remove all filler content so that it moves at a much faster pace, more closely following Akira Toriyama's original version from the comic. How much filler is being removed? The episode number is being reduced from 291 to 100!! This news doesn't bother me much, even as a fan I recognize that Dragon Ball had some pacing issues, I've heard the show referred to as Drag-On Ball many times, so this could be a good thing.
I'm pretty excited to see how these are going to look and sound, I've heard rumors that fan subtitlers are standing by to catch and release these as they air. If I get my hands on them, you'll find out here.
Another quick bit of unrelated Dragon Ball news, a brand new episode of Dragon Ball Z was released at the Jump Super Anime Tour in Japan not too long ago. It's the first "new" Dragon Ball animation to appear in 12 years. It takes place during the Majin Boo saga, and is titled Yo! Son Goku and His Friends Return. Here's more info and a download link (password required). Below is a trailer for Dragon Ball Kai.
