It is a constant struggle to keep up with the multiple delays of each and every Viz Big release for the series. It looks like Dragon Ball Z Viz Big #6 is getting pushed back from 19 January 2010 over to 16 February 2010. A single-month delay is not too bad for these releases, which have seen consecutive multi-month delays in the past.
This, in turn, pushes Dragon Ball Z Viz Big #7 from a supposedly-simultaneous release with #6 back over to 20 April 2010.
Apologies go out to those trying to keep up with the podcast’s “Manga Review of Awesomeness” via the most-cost-efficient Viz Big releases. This volume would have put you right where we are in our monthly series.
