The fourth Dragon Ball Kai Blu-ray box set was released yesterday, along with the next two DVD volumes. The Blu-ray box set contains episodes 40-54, which are presented in full screen and broken up onto five discs with three episodes per disc. The box set will set you back a pretty ¥19,950 (~$225), costing just a bit more than normal due to the extra 5th disc. I will note that the next Blu-ray box set is not scheduled to be released until sometime this October, which is one of the longest gaps between Blu-ray releases yet. In comparison to the Blu-rays, the Kai DVDs will run you a “measly” ¥2,940 (~$30), and instead are presented in the broadcast’s original widescreen aspect ratio. Picking up right where they left off last time, Volume #13 contains episodes 37-39, while Volume #14 contains the next three episodes, 40-42.

In addition, Happinet and Amazon Japan have already unveiled the cover art for next month’s set of Kai DVD volumes, both of which are set to be released 27 July 2010 for ¥2,940 (~$30). Volume #15 will contain episodes 43-45, while Volume #16 follows with the next three episodes, 46-48. Again, these DVDs are presented in the broadcast’s original widescreen aspect ratio.
