The DVD for the 2005 TV special "Angel's Tactics" will be released on 2005 October 21. As with the past two specials, a normal and limited edition release will be produced. The limited edition version will include a soundtrack CD.
CD Japan does not have a pre-order page available yet, but DiscStation does (limited) as does Amazon Japan (limited, regular).
The official Vap page also has not been updated to reflect this release date, so consider the date to be tentative (but likely correct) at this time.
